Meter Engineers 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.

Meter Engineers 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.
