Oval Gear Flow Meter
Flow measuring instruments
Introduction
Our Fuel Consumption System flow measuring instruments utilizes Tri-gear Flowmeters, known for their precision, reliability, and ruggedness. These advanced instruments accurately measure the volumetric flow of liquids in industrial, petroleum, and chemical applications which require high accuracy and repeatability. They operate on the Positive Displacement principle, offering a competitive alternative to Oval Gear, Sliding Vane, and Bi-Rotor options. Experience precise fuel consumption measurement and control with our cutting-edge system.
Operational Principal
Our advanced Fuel Consumption System, where the liquid flows into a single case measuring chamber, displacing two Tri gears. Each rotation of a Tri gear represents a discrete volume unit, and the gear speed directly correlates to the flow rate. Reed and Hall Effect sensors outside the pressure boundary detect Tri-gear Flowmeter movement, enabling local or remote instruments to display flow total, flow rate, or support batching applications. Meters can be fitted with additional sensors to provide in phase or out of phase signals for applications such as bidirectional flow. Experience precise and efficient fuel consumption monitoring with our cutting-edge system.

It is recommended that all "signal" cables are screened and run separately to power lines and switched inductive loads and are located well away from inverters and other "noisy" apparatus. Always use sound wiring practice. Both Hall effect and optical detectors (NPN) require a 10K Ohm external pull-up resistor connected between the output and a suitable power supply to attain a pulse. Typically the flowmeter PSU may be used but sometimes a dc pulse, which is of a different voltage, may be required e.g. using a PLC with a 24V PSU and an internal 5V rail for the pul-up

Tri Gear Flow Meter
Flow measuring instruments
Introduction
Tri-gear Flowmeters are precise, reliable and rugged instruments for the volumetric flow of liquids in general industrial, petroleum and chemical applications that require high degrees of accuracy and repeatability. They operate on the Positive Displacement principle using advanced gear technology and offer a competitive alternative to their Oval Gear, Sliding Vane and Bi-Rotor alternatives.
Operational Principal
Liquid Passes into the single case measuring chamber and displaces two Trigears. Each rotation of a Tri-gear Flowmeters is proportional to a discrete unit of volume, in turn, the speed at which the gears rotate is directly proportional to flowrate. Reed and Hall Effect sensors mounted outside the pressure boundary detect the movement of the Tri-gears, thus allowing local or remote instruments to display flow total, rate of flow or facilitate batching applications. Meters can be fitted with additional sensors to provide in phase or out of phase signals for applications such as bidirectional flow.
Benefits
- High Resolution Digital Output
- Wide Rangeability
- Bi-directional flow capability
- HART Output option
- Less slippage than oval gear meters.
- Smoother and quieter than Oval Gear Meters.
- Dual Output standard (reed and hall effect)
- Low Mass Tri-gears facilitate fast response time to step changes in flowrate.
