n: 1. a meter in which a piston is actuated by the pressure of a measured volume of liquid, and the volume swept by the piston is equal to the volume of the liquid recorded. 2. a meter in which the measuring element measures a volume of liquid by mechanically separating the liquid into discrete quantities of fixed volume and counting the quantities in volume units.

n: the portion of a displacement meter that contains the measuring element.

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 counting device. electrical or mechanical. coupled to the measuring element to register the indicated volume that has passed through the meter.

n: an instrument that measures fluid pressure and usually registers the difference between atmospheric pressure and the pressure of the fluid by indicating the effect of such pressures on a measuring element (e.g., a column of liquid, pressure in a Bourdon tube, a weighted piston, or a diaphragm).

n: the apparatus that measure the pressyre of fluid.

n: 1. a generator that produces repeating pulses or pulses initiated by signals. 2. a displacement meter accessory coupled to the measuring element and designed to produce a series of electrical pulses whose number is proportional to the volume measured and whose frequency is proportional to the flow rate. Also called pulser.
