INTRODUCTION
The MR flow transmitter is a state-of-the-art, microprocessor based variable area flow meter. It combines the rugged proven
technology of a piston-type, variable area flow meter with solid state circuitry including:
• Non-contact sensor electronics
• Electronic signal conditioning circuit
• Digital flow rate and total indication
• Proportional analog output
The product is sealed against industrial contamination by a NEMA 12 and 13 (IP 52/54) rated enclosure and is available for
either liquid or gas service.
The MR flow transmitter is capable of calculating and displaying both flow rate and total accumulated flow. The flow rate and
total flow can be displayed in any of the user selectable measurement units. The monitor’s large 8 digit numeric liquid crystal
display makes extended range viewing practical. The second 8 character alphanumeric display provides for selectable units
viewing in RUN mode and prompts for variables in PROGRAM mode.
All MR flow transmitters come pre-calibrated from the factory. However, the unit may be adjusted by the user to meet
specific system requirements. Calibration parameters are included for:
• Specific gravity compensation (all fluids)
• Viscosity compensation (petroleum-based fluids)
• Pressure and temperature compensation (pneumatic applications)
All meters include an analog output that can be configured for 0…5V DC, 0…10V DC, or 4…20 mA current loop. Applications
for the MR flow transmitter include:
• Bearing lubrication
• Case drain verification
• Gun drill and machine cooling
• Pump flow outputs

Installation Recommendations
The transmitter is a simple device to install. However, the following measures are recommended for reliable, trouble-
free operation:
• Align pipe accurately. Piping should be accurately aligned and of correct length. The high pressure body of the
transmitter can withstand shock and flow/pressure pulsation. However, the piping should be firmly supported by external
mounting brackets, both upstream and downstream of the meter, to avoid any pipe flexing actions that could reduce
meter life.
• Use rigid mounting. If the transmitter inlet or outlet are to be rigidly mounted, and the opposing port is to be connected
to flexible hose, the end connected with the flexible hose must be rigidly mounted.
• Use Teflon® tape for sealing NPT fitting.
• Install unions. Install a union near the inlet or outlet of the transmitter. This will facilitate quick, easy meter removal and
inspection during periodic maintenance procedures.
• Ensure the fluid is traveling in the direction of the flow arrow. See Figure 4.
OTE:NThe MR flow transmitter display board can be rotated 180° for optimal viewing. Simply remove the MR flow
transmitter cover, disconnect the ribbon cable, rotate the display board 180°, reconnect the ribbon cable, and
reinstall cover. See Figure 10 for cover screw tightening sequence.
• Use at least a 200 mesh (74 micron) filter. The transmitter will allow particulate to pass that would jam most valves and
flow controls. Systems that do not have filtration should be equipped with at least a 200 mesh (74 micron) filter. Most
hydraulic systems already have much finer filtration. Dirt, ferrous metal or sealing agents, such as Teflon® tape may lodge
and cause malfunction. If the meter is jammed at a fixed position, follow cleaning and maintenance instructions.
• Do not use thread locking compounds as thread sealant.
• Do not install the transmitter near turbulence producing fittings such as elbows, reducers, or close coupled valves. The
transmitter does not require flow straighteners or special lengths of straight inlet/outlet piping to stabilize turbulent
flow patterns. However, to assure maximum operational reliability, avoid installation of elbows, valves and/or reducers
immediately adjacent to the meter inlet.
• Do not install the transmitter near fast-acting valves. Fast-acting valves have the potential to create high magnitude
hydraulic pressure spikes. These spikes can damage the internal components of the meter, resulting in inaccuracies
or malfunction.
• Do not allow unidirectional transmitters to be operated against the direction of the flow arrow. The standard transmitter
is a unidirectional flow meter. The piston acts as a check valve to block flow in the reverse direction. This causes an
excessive pressure differential, which can result in damage to internal meter components. The transmitter is also available
in a modified design, which offers a reverse flow bypass feature to accommodate bidirectional flow.
OTE:NTransmitters with a reverse flow bypass feature are available. Consult factory for details.
Electrical Connections
Cable may be shortened or lengthened as required for proper installation. The cable is soldered directly to the electrical
connector at the factory.
Cable replacement requires disassembly of the electrical connector.

MAINTENANCE
BEFORE ATTEMPTING TO REMOVE THE TRANSMITTER FROM THE LINE, CHECK THE SYSTEM TO CONFIRM THAT LINE
PRESSURE HAS BEEN REDUCED TO ZERO PSI. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS
PERSONAL INJURY OR DEATH AND/OR DAMAGE TO THE EQUIPMENT.
DISCONNECT ELECTRICAL POWER BEFORE REMOVING METER COVER. FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH AND/OR DAMAGE TO THE EQUIPMENT.
Cartridge Cleaning
1. Disconnect the transmitter cable.
2. Remove the meter from the line. Remove excess piping from the transmitter. See Figure 4 and Figure 5.
OTE:NIt is not necessary to remove the aluminum housing from the transmitter to remove it from the line.
3. Thoroughly wipe o the entire transmitter surface using mild detergent or isopropyl alcohol.
DO NOT USE AROMATIC HYDROCARBONS, HALOGENATED HYDROCARBONS, KETONES OR ESTER BASED FLUIDS ON
POLYCARBONATE LENS. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE TRANSMITTER.
4. Remove the inlet port cap, wave spring, retaining ring, and cone assembly from the transmitter body (Figure 9).
5. Gently push the body towards the outlet port.
6. The piston, inner magnet and transmitter spring are secured within the transmitter body with a retaining ring. Remove the
retaining ring with a small screwdriver, then the internal components can be removed from the body (Figure 9).
OTE:NIf internal parts do not slide freely from cartridge, use a wooden dowel inserted into the outlet port of the meter to
push parts out.
7. Place all parts on a clean work surface. Clean and inspect all parts. Replace any that appear worn or damaged. Check inlet
port O-ring for damage and replace if required.
FIELD REPLACEMENT OF THE SPRING, METERING CONE AND/OR PISTON/MAGNET ASSEMBLY MAY RESULT IN CHANGES
TO THE CALIBRATION OF THE FLOW METER.
8. Reassemble the transmitter by inserting the transmitter spring into the body, followed by the piston/inner magnet
assembly. A slight compression of the piston against the spring is required during installation of the retaining ring.
9. Gently push body assembly into the outlet end of the transmitter enclosure. The at surface of the body output port
should be ush with the transmitter enclosure opening.
10. With the transmitter positioned vertically on a at surface, inlet port facing up, install the transmitter cone assembly and
wave spring into the body and secure with the inlet port end cap.
11. Reinstall transmitter to the line. Reconnect electrical power.
Inspection
1. Frequent inspection should be made. The environment and frequency of use should determine a schedule for
maintenance checks. It is recommended that it should be at least once a year.
2. Perform visual, electrical, and mechanical checks on all components on a regular basis.
3. Visually check for undue heating evidence such as discoloration of wires or other components, damaged or worn parts, or
leakage evidence such as water or corrosion in the interior.
4. Make sure all electrical connections are clean and tight and that the device is wired properly.

APPLICATION INFORMATION, LIQUID
Viscosity Eect (SUS/cSt)
The design uses a precision machined, sharp- edged orifice and biasing calibration spring that assures operating stability and
accuracy over the wide viscosity range common to many fluids. Generally, high flow models of each meter size provide good
accuracy over a viscosity range of 40…500 SUS (4.2…109 cSt).
Density Eect (specic gravity)
Any fluid density change from stated standards has a proportional effect on meter accuracy. Corrections for more or less
dense fluids can be made to standard scales using the following correction factor:
10.
Specic Gravity For water/water-based meters
0 876.
Specic Gravity For petroleum-based meters
Application Information Pneumatic
OTE:NPressure and temperature readings must be taken at the flow meter inlet to ensure accurate correction factors.
The pneumatic flow meter is calibrated for air in standard cubic feet per minute (scfm) at 1.0 s.g. (70° F @ 100 psi), and liter per
second (lps) at 1.0 s.g. (21° C @ 6.9 bar).
