Double Case PD Meters

Double Case Positive Displacement Meters

The most accurate for volume measurement, Smith Meter® Double Case Positive Displacement Meters utilize a rotary-vane principal to obtain direct measurements from the flow stream without relying on inference technology.  Smith Meter PD meters use a stream-lined flow path to minimize pressure drop across the measuring chamber.  This provides inherent accuracy in the design and operation of the meters.  Engineered to operate with low pressure drop and low slippage, Double Case meters maintain superior accuracy and stability and continue to be the meter by which all other meters are compared.
