Metering Solutions range of oil flow meters is used for liquid consumption monitoring and dosing applications.  This range of fuel flow meters uses the Oval Gear, Nutating Disc Technology or Turbine operating principle.

Nutating Disc Technology

During each cycle, an amount of liquid is displaced equal to the difference in the volumes of the chambers minus the volumes of the pistons.  This process repeats itself in a continuous flow mode at the rates of 1 to 210 complete cycles per second proportionately to the fluid flow through the meter.

Oval Gear Technology

Positive displacement flowmeters repeatedly entrap 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.

Turbine Technology

They basically comprise of three component assemblies, fitted inside a flow meter body (locked with an internal circlip), which has a magnetic pick up fitted and come in a range of threaded, flanged or wafer (designed for between flange installations) styles.  The Rotor & Shaft assembly which is mounted between journal bearings inside the Rotor Shaft Support assemblies is turned by the kinetic energy of the flowing fluid at an angular velocity, which in the linear range of the Flowmeter is proportional to the mean axial velocity of the fluid.  The Rotor blades sweep out the full bore of the meter except for a small tip clearance space. As the blade tips pass the magnetic pick up they initiate a pulse. Flow rate is determined by the frequency of the pulses and Totalised Flow is obtained by summing the pulses.
