n: a velocitymeasuring device in which gas flow is parallel to the rotor axis and the speed of rotation is proportional to the rate of flow.

n: 1. the portion of a displacement meter that moves within the measuring chamber so as to divide the liquid into measured segments as the liquid passes through the meter. 2. the rotating member of a turbine meter, commonly referred to as the rotor.

n: a turbine meter field check to determine the relative level of mechanical friction in a meter.

n: the use of a master meter to calibrate positive-displacement and turbine meters measuring gas flow.

n: a velocity-measuring device for fluids in which the flow is parallel to the rotor axis and the speed of rotation is proportional to the rate of flow. The volume of gas in gas measurement is determined by counting the revolutions of the rotor. In liquid turbine meter measurement, the meter and electronic instrumentation are combined to measure total flow and/or flow rate within the piping system.
