Volumetric / Rotary Piston Technology
Metering Solutions range of oil flow meters is used for liquid consumption monitoring and dosing applications.  This oil flow meter uses Volumetric / Rotary Piston operating principle which work on the volumetric principle of rotary piston meters (positive displacement meters).  The main features of this measuring principle are large measuring ranges, high accuracy, suitability for high viscosities and independence from power supply; flow disturbances do not influence proper operation.  Rotary piston, guide roller and drive are the only moving parts in contact with the liquid. Their movement is transmitted by a magnetic coupling through a sealing plate. The hydraulic part is completely separated from the totalising module.

Oval Gear Technology

Metering Solutions range of oil / fuel flow meters is used for liquid consumption monitoring and dosing applications.  These types of oil / fuel flow meters use the Oval Gear operating principle which repeatedly entraps fluid to measure its flow. It can be thought of as repeatedly filling a bucket with fluid before dumping the contents downstream. The number of times that the bucket is filled represents the flow. Many positive displacement flowmeter geometries are available. Entrapment is usually accomplished using rotating parts that form moving seals between each other and/or the flowmeter body. In most designs, the rotating parts have tight tolerances so these seals can prevent fluid from going through the flowmeter without being measured (slippage). In some positive displacement flowmeter designs, bearings are used to support the rotating parts. Rotation can be sensed mechanically or by detecting the movement of a rotating part. When more fluid is flowing, the rotating parts turn proportionally faster. The electronic transmitter processes the signal generated by the rotation to determine the flow of the fluid. Some positive displacement flowmeters have mechanical registers that show the total flow on a local display.
