PRIME 4 Installation and Operation Manual 1 Overview The Smith Meter PRIME 4 meter is a rotary positive-displacement meter that measures product flow in two directions. The accurately machined housing contains a rotor which revolves on tungsten carbide bearings and carries two evenly spaced Polyketone blades. As liquid flows through the meter, the rotor and blades revolve about a fixed cam, causing the blades to reciprocate. - Page 5 PRIME 4 Installation and Operation Manual In the example below, a quarter revolution has been made. Blade A is still extended and blade B is now fully extended. An exact known volume of new liquid is now in the measuring chamber. One-eighth of a revolution later, the measured liquid moves out of the meter.
