Bidirectional Prover

 Smith Meter Bidirectional Provers are stationary or portable displacement-type meter proving devices. When connected in series with a meter, the number of meter pulses generated during the round trip displacement of the prover-calibrated (water drawn) volume yields accurate meter factor.

The Smith Meter Bidirectional Prover may be used to calibrate positive displacement or turbine meters in virtually any application including loading rack installations, pipelines, barge loading/unloading systems, etc. These provers may be used on most liquid petroleum products such as LPG, gasolines, and crude oils which have varying viscosities and lubricating qualities.
