Precision flow meters to cover any flow, any viscosity
From flows of less than 1 cc/min to viscosities of more than 1 million cP, our wide ranging piston, gear and helical rotor positive displacement flow meters provide a level of performance that the competition can’t match.
Piston Flow Meters
Offering the highest accuracy (0.2% of reading), widest flow range, 200:1 or more, smallest displacements and the tightest fits and tolerances making them suitable for low viscosity liquids. Consider the piston family for fuel measurement, hydraulic test stands, additive injection or any wide range application Compare
Gear Flow Meters
An economical yet rugged, high pressure design with 0.3% of reading accuracy, 100:1 flow range or more. Ideal for fuel oil measurement, hydraulic test stands, hot melt adhesives or conformal coatings. Compare
Helical Flow Meters
Measuring the highest flow rates and viscosities while offering 0.2% of reading accuracy, 100:1 flow range or more and the lowest pressure drop. Ideal for lube oils, hydraulic test stands, urethane foam blending, greases or molten adhesives Compare

The viscosity of 200°F Turbo Oil is too low for gear meters. The internal clearance along the side of the gear allows too much blow-by for them to be accurate at less than 5 cps.
Quoted: Model 213 Piston meter with 1/5th the internal clearance. The Model 213 is used extensively to measure the flow rate of low viscosity fluids such as gasoline, freon and hot turbo oil.
A 10% oil-in-water solution to be applied through a pulsing flow of 30 to 120 ccm.
Quoted: Model G004 with its high-resolution, 500 pulses/cc output. Monitors per shot application and average flow rate.
Polymer with a 15k to 22k cps viscosity, used as part of enhanced recovery in the mining industry, must be controlled in the range of 0.1 to 1 liter/minute.
Quoted: Model 241 with 4-20 mA output transmitter. The high resolution Model 295 transmitter can produce a full scale output at low meter RPM's. Up-sizing the meter to handle the viscosity does not sacrifice the low flow resolution.
Neoprene trim is available in the Piston type meters to fit the material compatibility requirements for Freon®.
Sold: Model 214-411-715 meter for use in a HFC charging stand. The tight internal fit of the Max piston meters makes them suitable for measuring low viscosity Freon®. By specifying the option of Neoprene seals, the system has full material compatibility.
Critical measurement of small flow rates in a fuel stream, combined with a high temperature and pressure requirement.
Sold: Four sets of the Model 213 meter with a pressure rating of 210 bar combined with a 290 Series transmitter with a 155°C temperature rating.
Four high temperature fluids are melted and held at process temperature using steam tracing
Quoted: A special combination of a Model 213 flow meter with a heat ported base and an aluminum magnet shield for rapid heat transfer. High-temperature, Model 294-280 transmitter provides a 4-20mA output.
Hydraulic oil flow of 130 LPM will be used to fill and empty a hydraulic ram attached to a water controlling sluice gate. Full open and closed positions rely on sensors, intermediate positions will be verified by totalization of flow.
Quoted: Model G240 with quadrature output transmitter. Sensor provides 7000 pulses/L for high resolution control and placement. Customer interest was based on a similar application in the aluminum casting industry .
A fuel pump manufacturer who's design required that the flow testing be done at the pump inlet. The range was 3 liters/hour and less.
Sold: Model 213 flow meter with a Model 295 voltage output transmitter. The smoothly rotating, Model 213 does not impede the flow on the suction side of the pump and is capable of measuring as low as 0.06 L/hr.
Testing valve leakage against a "less than 0.25 cc/min" specification
Quoted: Model P002 piston flow meter with a 6000 psi rating and 1000 pulses/cc output. Pulse counter with a 4 pulse/second threshold to determine Pass/Fail
Replacing long pot life adhesives with on-the-fly blending of 2K adhesive and catalyst. Catalyzed system offers precise cure characteristics.
Quoted: Two Model G015 gear flow meters for the resin and a Model 213 piston flow meter for the catalyst.
Customer needs to verify 120 shot/minute adhesive dispensing between plastic seal and metal bottle cap. The normal method of UV detection cannot see into the blind hole.
Quoted: Model G015 flow meter with its 200 pulse/gram resolution is ideal for the 0.25 gram shots.
Natural Gas odorization injection meters that have suffered from power surges on the signal line are being upgraded to protect their circuitry.
Sold: Model EX295 transmitter upgrade to replace the Model 286 transmitters used in outdoor applications.
An international customer is seeking to upgrade a military test stand.
Quoted: Model G240 flow meter with ATEX approved transmitter for hazardous location use.
Measuring fuel to automotive heaters over any temperature between -40 to +120°C.
Quoted: Model 213 flow meter with two part Model 295 transmitter
With viscosity ranges from 2 to 3000 cps and temperature ranges from -40 to +150°C.
Quoted: Model 241 flow meter with high temperature Model 294 transmitter
Explosion proof rated injection system with pressures up to 200 bar and temperatures up to 120°C.
Quoted: Model 213 flow meter with EX295 transmitter with UL and ATEX certification
