Unidirectional Meter Provers

Meter Engineers, Inc. has developed a unique unidirectional meter prover that eliminates many of the problems other unidirectional prover
designs encounter.

MEI’s unique interchange design ensures positive sphere launch every time. It eliminates the sphere buoyancy problems causing
the sphere to mis-launch. The interchange also includes a clean out line preventing trash from getting in the prover and causing
damage to the coating, seals or pipe.

MEI’s unidirectional prover is ideal for high volume installations where single or multiple products are handled.

The seal mechanism is designed to receive very little wear from operation and has been proven to last for many years.

Meter Engineers can also design a unidirect prover suited to your specifications. Please submit our Online Prover Information Form
