Introduction The INVALCO Turbine Flowmeter is a device used to measure the volumetric flow of a fluid. The flowmeter consists of the body, a multiblade rotor (usually 6 to 10 blades depending on size), bearings and s for the rotor. As a fluid es through the flowmeter the rotor spins. The speed of the rotor is directly proportional to the fluid velocity or flow rate. As the rotor spins, the balde tips through a magnetic field generated by permanent magnets in a pickup coil mounted in close proximity to the rotor but separated from it and the process fluid by the wall of the flowmeter body. Each time a blade es the magnet, it generates a small alternating current in the pickup coil. (See Figure 7) The pickup coil is attached to the pickup by two terminals or wires. Each rotor blade ing through the magnetic pickup flux lines produce one alternating current cycle. Depending on the flowmeter size, a certain number of pulses are produced for each volumetric unit of liquid ing through the turbine flowmeter. This is known as the “K-Factor” of the turbine flowmeter. The variation of this factor over the specified flow range is the Linearity or accuracy of the flowmeter.
Mechanical Installation Turbine Flowmeters are affected by upstream and downstream piping configurations. Upstream piping has a pronounced effect on flowmeter performance making it necessary to have ten (10) straight pipe diameters upstream of the turbine flowmeter and five (5) pipe diameters downstream of the turbine flowmeter. Flowmeters should be installed with the arrow marked on the body pointing in the direction of flow.
Figure 1
Control valves should always be located downstream from the flowmeter. If a line is empty and a valve is opened, the high velocity fluid stricking the flowmeter can cause severe damage. Air eliminators should be used in cases where gases are flowing in the process stream. Air in the liquid will cause the flowmeter rotor to spin at a different rate than the liquid giving incorrect readings. Spools should be installed in the flowmeter position during start up to prevent damage to the flowmeter from solids (welding slag, rust, scale, etc.) in the process liquid. Note: Meter should be installed with ten diameters of straight pipe the same size as turbine meter bore up and 5 straight pipe diameters downstream of meter. Note: If valve is to be used, it must be downstream from the meter. This is necessary not only to keep the line full for accuracy in batching applications, but to prevent damage caused by striking an empty meter with a high velocity stream. Note: Sleeved bearings used in INVALCO flowmeters are lubricated with the process fluid. Never spin the flowmeter at high speeds with air. Always confirm that the flow line contains fluid at start up. The life of the flowmeter can be extended by using a mesh filter in the flow line. Table I shows the recommended filter for various sizes of flowmeters. Table 1 Turbine Flowmeter Size 1/2” 3/4” 1” 1-1/2” 2” 2

Installation (con’t)
Turbine Meter Maintenance
Electrical Installation (Figure 2) Thread the magnetic pickup into the mounting boss located on the top of the flowmeter. If the pickup does not have wire leads included, connect the signal cable to the pickup by threading on the keyed connector. Note: Hand Tighten Only. Use of tools to tighten the pickup can damage the flowmeter and pickup.
Removal of Flowmeter Internals Cartridge Type Sizes 3/4 Inch through 2” (Figure 3) The cartridge type turbine flowmeter utilizes internals assembled into a single part, eliminating the need for the three part internals kit. Note: This type of internals is not interchangeable with any other body type. 1) Remove the magnetic pickup. 2) Identify the upstream end of the meter by locating the two grooves visible from the outside of one end. 3) Remove the retaining ring from the end of the flow meter identified by the grooves. 4) Slide the internals out of the flowmeter. It may be necessary to push the internals out by gently applying pressure to the opposite end. 5) Inspect the internal bore of the flowmeter for defects. The internal surface of the flowmeter should be smooth. If the surface is damaged, the flowmeter body should be replaced. 6) Inspect the internals kit for damage or wear. If it appears to be damaged, replace it with a new internals kit.
Figure 3 Figure 2
Replacement of Flowmeter Internals Cartridge Type Sizes 3/4 Inch through 2 Inch 1) Identify the upstream end of the turbine flowmeter by locating the two grooves visible from the outside of one end. 2) Identify the upstream end of the turbine flowmeter internals by locating the end with a cone recessed between two s forming a “V”. 3) Insert the end opposite of the recessed cone into the groooves located in the upstream end of the turbine flow meter body. 4) Slide the flowmeter internals into the turbine flowmeter body until it seats firmly against the downstream end. 5) Insert the retaining ring into the upstream end of the turbine flowmeter, pushing it far enough into the flowmeter body to engage the retaining ring slot directly above the turbine flowmeter internals.

Removal and Replacement of Flowmeter Internals Size 4 Inch (Shipped Before April 1990) and Size 3 Inch Shipped Before January 1989 1) Locate the flow direction arrow on the turbine flow meter body, or the words “Inlet” or “Outlet” stamped near the ends. Set the flowmeter body on end with the outlet map. 2) Assemble the rear assembly, giving attention to aligning the grooves in the pinion bolt with the slots in the cage. 3) Install the lock washer and nut. The threads on the pinion bolt should only extend halfway through the nut, (about 2-1/2 turns). 4) Insert three vanes with the tapered bottom edges matching the sloping bottom of the grooves in the pinion bolt. 5) Locate the three wide and shallow grooves running in a length-wise direction in the turbine flowmeter body. 6) Insert the assembly into the body, bearing end first, with the vanes sliding down the shallow grooves. The assembly will come to rest against a shoulder. 7) Rotate the entire assembly about 60 degrees, so that the vanes are no longer lines up with the access grooves in the body. 8) Tighten the nut slowly, working the assembly back and forth so the vanes will seat properly. Tighten the nut secruely. 9) Turn the body over and slip the rotor onto the rear bearing just installed. 10) Assemble and install the front in the same manner. It may be necessary to pull or push on the pinion bolt to work the assembly in far enough to read the shoulder, before rotating. The pinion bolt is pulled back, the vanes are forced outward. The rear pinion bolt can be identified by the 1/2 inch diameter carbide bearing which protrudes 1-7/32 inches. The rear pinion body, or cage, can be identified as follows: 4 inch flowmeter front and rear cages are identical. 3 inch (shipped before January 1989) front cage overall length is 2-21/32 inches and the slots begin 3/8 inches from the open end. Rear cage overall length is 2-15/16 inches and the slots begin a little over 3/4 inch from the open end.
Removal of Flowmeter Internals Size 4 Inch (Figure 5) 1) Remove the internals by retracting the set screw and rapthe sliding vane, if necessary, to relieve the locking pressure. 2) If spirolox rings are installed, remove them before attempt ing to remove the s. 3) Remove the rotor fromt he flowmeter. 4) Remove the rotor from the flowmeter. 5) Repeat steps 1 through 3 to remove the second . Replacement of Flowmeter Internals Size 4 Inch (Figure 5) 1) If your flowmeter body is grooved for spirolox rings, it is recommended that the rings be installed. Note: Lock rings are provided to absorb shock and should be replaced when replacing the internals. 2) Advance the sliding vane with the set screw until the whole assembly fits closely in the bore of the flowmeter body. 3) Position the assembly against the shoulder in the flowmeter body and tighten the set screw. 4) Install a spirolox ring if a groove has been provided for. 5) Meter bodies shipped after December 1, 1970 have three grooves machined in each end. The sliding vane has an “ear”, detail “B”, to engage one of these grooves. The front assembly should be positioned so that the sliding vane engages the upper-left-hand groove. The sliding vane on the rear should engage the upper-right-hand groove. Both sliding vanes should be in line. 6) For installation in older bodies (prior to December 1, 1970), which are not grooved, the sliding vane can be turned upside down (Figure 5) so the ear is buried in the .

Magnetic Pickups Flow in the turbine flowmeter is sensed by a non-wetted sensor called a variable reluctance magnetic pickup. The magnetic pickup is an assembly consisting of a permanent magnet and a coil bobbin on which several hundred turns of wire are wound (Figure 6). This combination produces a magnetic field at the top of the pickup. The pickup is placed in close proximity to the rotor blades, but is separated from it and the process fluid by the wall of the flowmeter housing. As the rotor turns, the blades disrupt the magnetic field of the pikcup and generate a sine wave voltage signal across the terminals of the magnetic pickup coil. Each time a rotor blade es through the magnetic field, one alternating current (AC) cycle is generated (Figure 7). The number of pulses produced by a turbine flowmeter per gallon of water is known as the “K-Factor”.

3-A Sanitary Meters/Internals The INVALCO 3-A (28-03) Sanitary Turbine Flow meter is certified for use in the food and beverage industry where 3-A is required. The meter has been specially designed to have the same characteristics, flow ranges, and life as all the Invalco industrial meters, and also meet or exceed the requirement of 3-A (28-03). The meter has a maximum surface finish of 32ra on all internal parts; all components are manufactured out of 3-A approved material, and can be cleaned in place to save time and money in disassembling cleaning and reassembling the meter. The wear surfaces are made from FDA (3-A) approved carbide for superior wear resistance. The meter can be cleaned as long as the following conditions are met: ! Caustic solutions that are acceptable with 316 stainless steel components ! Temperatures of less than 275ºF (135ºC) for less than a 60 minute duration ! Instantaneous flow Ranges of the fluids must never exceed the chart below. Meter Size 3/4 1 1 1/2 2 3 ! !

Flow Range (GPM) 1.5-15 6.5-65 17.5-175 33-330 60-600
Air purging must be done with care not to create severe shock loading to the meter, and velocity through the meter must not exceed the instantaneous published flow ranges of the meter. Radii at ends of meters and the thrust bearing pockets (see figure 14) must be periodically checked for cleanliness and adjustments in cleaning may be required to clean these areas. If areas do not clean in place the meter may need to be disassembled from the line and cleaned by hand or other method to insure proper cleanliness is being achieved. If the meter is disassembled for cleaning or inspection, care must be taken not to lose the thrust bearings located at either end of the shaft. All replacement internals utilize a sanitary paste to ensure that the bearings remain in place during assembly.

The 4200s are affected by EMF (Electric Magnetic Fields); due to this the unit needs to be located in an area with little affects from externally omitting EMF devices. The turbine and pickup uses EMF in pulses to calculate rate. Interference in this field by other devices will cause inaccuracies with the meter. Electric motors, spark driven engines, transformers, and other high current or high voltage devices create EMF and should be kept as far away as feasible to lessen their chances of effecting the meter. Vibration can cause false readings or counted rate when not in use. Portable units should be reset after transport to re-zero the meter. Place meter in a location where it is well grounded, free of vibration and stable when metering.

Introduction The INVALCO Turbine Flowmeter is a device used to measure the volumetric flow of a fluid. The flowmeter consists of the body, a multiblade rotor (usually 6 to 10 blades depending on size), bearings and s for the rotor. As a fluid es through the flowmeter the rotor spins. The speed of the rotor is directly proportional to the fluid velocity or flow rate. As the rotor spins, the balde tips through a magnetic field generated by permanent magnets in a pickup coil mounted in close proximity to the rotor but separated from it and the process fluid by the wall of the flowmeter body. Each time a blade es the magnet, it generates a small alternating current in the pickup coil. (See Figure 7) The pickup coil is attached to the pickup by two terminals or wires. Each rotor blade ing through the magnetic pickup flux lines produce one alternating current cycle. Depending on the flowmeter size, a certain number of pulses are produced for each volumetric unit of liquid ing through the turbine flowmeter. This is known as the “K-Factor” of the turbine flowmeter. The variation of this factor over the specified flow range is the Linearity or accuracy of the flowmeter.
Mechanical Installation Turbine Flowmeters are affected by upstream and downstream piping configurations. Upstream piping has a pronounced effect on flowmeter performance making it necessary to have ten (10) straight pipe diameters upstream of the turbine flowmeter and five (5) pipe diameters downstream of the turbine flowmeter. Flowmeters should be installed with the arrow marked on the body pointing in the direction of flow.
Figure 1
Control valves should always be located downstream from the flowmeter. If a line is empty and a valve is opened, the high velocity fluid stricking the flowmeter can cause severe damage. Air eliminators should be used in cases where gases are flowing in the process stream. Air in the liquid will cause the flowmeter rotor to spin at a different rate than the liquid giving incorrect readings. Spools should be installed in the flowmeter position during start up to prevent damage to the flowmeter from solids (welding slag, rust, scale, etc.) in the process liquid. Note: Meter should be installed with ten diameters of straight pipe the same size as turbine meter bore up and 5 straight pipe diameters downstream of meter. Note: If valve is to be used, it must be downstream from the meter. This is necessary not only to keep the line full for accuracy in batching applications, but to prevent damage caused by striking an empty meter with a high velocity stream. Note: Sleeved bearings used in INVALCO flowmeters are lubricated with the process fluid. Never spin the flowmeter at high speeds with air. Always confirm that the flow line contains fluid at start up. The life of the flowmeter can be extended by using a mesh filter in the flow line. Table I shows the recommended filter for various sizes of flowmeters. Table 1 Turbine Flowmeter Size 1/2” 3/4” 1” 1-1/2” 2” 2

Installation (con’t)
Turbine Meter Maintenance
Electrical Installation (Figure 2) Thread the magnetic pickup into the mounting boss located on the top of the flowmeter. If the pickup does not have wire leads included, connect the signal cable to the pickup by threading on the keyed connector. Note: Hand Tighten Only. Use of tools to tighten the pickup can damage the flowmeter and pickup.
Removal of Flowmeter Internals Cartridge Type Sizes 3/4 Inch through 2” (Figure 3) The cartridge type turbine flowmeter utilizes internals assembled into a single part, eliminating the need for the three part internals kit. Note: This type of internals is not interchangeable with any other body type. 1) Remove the magnetic pickup. 2) Identify the upstream end of the meter by locating the two grooves visible from the outside of one end. 3) Remove the retaining ring from the end of the flow meter identified by the grooves. 4) Slide the internals out of the flowmeter. It may be necessary to push the internals out by gently applying pressure to the opposite end. 5) Inspect the internal bore of the flowmeter for defects. The internal surface of the flowmeter should be smooth. If the surface is damaged, the flowmeter body should be replaced. 6) Inspect the internals kit for damage or wear. If it appears to be damaged, replace it with a new internals kit.
Figure 3 Figure 2
Replacement of Flowmeter Internals Cartridge Type Sizes 3/4 Inch through 2 Inch 1) Identify the upstream end of the turbine flowmeter by locating the two grooves visible from the outside of one end. 2) Identify the upstream end of the turbine flowmeter internals by locating the end with a cone recessed between two s forming a “V”. 3) Insert the end opposite of the recessed cone into the groooves located in the upstream end of the turbine flow meter body. 4) Slide the flowmeter internals into the turbine flowmeter body until it seats firmly against the downstream end. 5) Insert the retaining ring into the upstream end of the turbine flowmeter, pushing it far enough into the flowmeter body to engage the retaining ring slot directly above the turbine flowmeter internals.

Removal and Replacement of Flowmeter Internals Size 4 Inch (Shipped Before April 1990) and Size 3 Inch Shipped Before January 1989 1) Locate the flow direction arrow on the turbine flow meter body, or the words “Inlet” or “Outlet” stamped near the ends. Set the flowmeter body on end with the outlet map. 2) Assemble the rear assembly, giving attention to aligning the grooves in the pinion bolt with the slots in the cage. 3) Install the lock washer and nut. The threads on the pinion bolt should only extend halfway through the nut, (about 2-1/2 turns). 4) Insert three vanes with the tapered bottom edges matching the sloping bottom of the grooves in the pinion bolt. 5) Locate the three wide and shallow grooves running in a length-wise direction in the turbine flowmeter body. 6) Insert the assembly into the body, bearing end first, with the vanes sliding down the shallow grooves. The assembly will come to rest against a shoulder. 7) Rotate the entire assembly about 60 degrees, so that the vanes are no longer lines up with the access grooves in the body. 8) Tighten the nut slowly, working the assembly back and forth so the vanes will seat properly. Tighten the nut secruely. 9) Turn the body over and slip the rotor onto the rear bearing just installed. 10) Assemble and install the front in the same manner. It may be necessary to pull or push on the pinion bolt to work the assembly in far enough to read the shoulder, before rotating. The pinion bolt is pulled back, the vanes are forced outward. The rear pinion bolt can be identified by the 1/2 inch diameter carbide bearing which protrudes 1-7/32 inches. The rear pinion body, or cage, can be identified as follows: 4 inch flowmeter front and rear cages are identical. 3 inch (shipped before January 1989) front cage overall length is 2-21/32 inches and the slots begin 3/8 inches from the open end. Rear cage overall length is 2-15/16 inches and the slots begin a little over 3/4 inch from the open end.
Removal of Flowmeter Internals Size 4 Inch (Figure 5) 1) Remove the internals by retracting the set screw and rapthe sliding vane, if necessary, to relieve the locking pressure. 2) If spirolox rings are installed, remove them before attempt ing to remove the s. 3) Remove the rotor fromt he flowmeter. 4) Remove the rotor from the flowmeter. 5) Repeat steps 1 through 3 to remove the second . Replacement of Flowmeter Internals Size 4 Inch (Figure 5) 1) If your flowmeter body is grooved for spirolox rings, it is recommended that the rings be installed. Note: Lock rings are provided to absorb shock and should be replaced when replacing the internals. 2) Advance the sliding vane with the set screw until the whole assembly fits closely in the bore of the flowmeter body. 3) Position the assembly against the shoulder in the flowmeter body and tighten the set screw. 4) Install a spirolox ring if a groove has been provided for. 5) Meter bodies shipped after December 1, 1970 have three grooves machined in each end. The sliding vane has an “ear”, detail “B”, to engage one of these grooves. The front assembly should be positioned so that the sliding vane engages the upper-left-hand groove. The sliding vane on the rear should engage the upper-right-hand groove. Both sliding vanes should be in line. 6) For installation in older bodies (prior to December 1, 1970), which are not grooved, the sliding vane can be turned upside down (Figure 5) so the ear is buried in the .

Magnetic Pickups Flow in the turbine flowmeter is sensed by a non-wetted sensor called a variable reluctance magnetic pickup. The magnetic pickup is an assembly consisting of a permanent magnet and a coil bobbin on which several hundred turns of wire are wound (Figure 6). This combination produces a magnetic field at the top of the pickup. The pickup is placed in close proximity to the rotor blades, but is separated from it and the process fluid by the wall of the flowmeter housing. As the rotor turns, the blades disrupt the magnetic field of the pikcup and generate a sine wave voltage signal across the terminals of the magnetic pickup coil. Each time a rotor blade es through the magnetic field, one alternating current (AC) cycle is generated (Figure 7). The number of pulses produced by a turbine flowmeter per gallon of water is known as the “K-Factor”.

Flow Range (GPM) 1.5-15 6.5-65 17.5-175 33-330 60-600
Air purging must be done with care not to create severe shock loading to the meter, and velocity through the meter must not exceed the instantaneous published flow ranges of the meter. Radii at ends of meters and the thrust bearing pockets (see figure 14) must be periodically checked for cleanliness and adjustments in cleaning may be required to clean these areas. If areas do not clean in place the meter may need to be disassembled from the line and cleaned by hand or other method to insure proper cleanliness is being achieved. If the meter is disassembled for cleaning or inspection, care must be taken not to lose the thrust bearings located at either end of the shaft. All replacement internals utilize a sanitary paste to ensure that the bearings remain in place during assembly.

The roll over total screen displays a “r” in the left most position and then any digits in excess of the six that are normally viewable. K-factor is viewable by pressing the k-factor button on the keypad, and pressing the k-factor button again will return to the Totalizing display. Software Version is viewable by pressing the “+” button on the keypad Program Steps 1. Hold the “Program” button for 5 seconds. This will put the 4200 into programming mode. 2. The first time that the 4200 is setup, the program will take you directly to the K-factor entry screen. The 4200 will now prompt for using a single K-factor or to linearize using multiple K-factors. Selecting “oFF” will use a single K-factor (go to Step 3). Selecting “on” will allow the input of multiple K-factors (go to Step 4).
Button operation: “Program” = progress to next screen regardless of where cursor is positioned “Enter/Next” = move cursor left one position “K-factor” = move cursor right one position “+” = increments number where cursor is positioned “-” = decrements number where cursor is positioned “Reset” = replaces numbers with default and returns the cursor to the right most position 3. Input the appropriate K-factor. Insertion of the decimal position is the last step required to input a new k-factor. After the last numerical position is entered, the “+” and “-” buttons will move the decimal position through the 3 positions. After placing the decimal in the correct position, the “Enter/Next” button will progress the screen. If linearization is required proceed to Step 4. If linearization is not required proceed to Step 7.

The 4200s are affected by EMF (Electric Magnetic Fields); due to this the unit needs to be located in an area with little affects from externally omitting EMF devices. The turbine and pickup uses EMF in pulses to calculate rate. Interference in this field by other devices will cause inaccuracies with the meter. Electric motors, spark driven engines, transformers, and other high current or high voltage devices create EMF and should be kept as far away as feasible to lessen their chances of effecting the meter. Vibration can cause false readings or counted rate when not in use. Portable units should be reset after transport to re-zero the meter. Place meter in a location where it is well grounded, free of vibration and stable when metering.
Installation Wall Mounting A wall mounting bracket is supplied with each instrument. The instrument is then attached to the bracket at the bottom with knobs. Removing the Front : The front of the instrument is removed as follows: 1. Loosen knobs and tilt unit down. 2. Undo the eight screws retaining the front . 3. Pull the front free from the housing. Unit can then be tilted up to access internal components.
