As meters continue to be used over time, the meter’s measurement accuracy
deteriorates. Many things can cause the flow sensor bearings to wear down
beyond specified limits so that meters are measuring lower volume levels
causing producers to pump more oil than the consumer is buying. Meter Provers
have a “Known Traceable Volume” which allows using actual flowing and
operating conditions to establish a meter correction factor to restore
measurement accuracy.
There are 4 types of provers. This chapter will give a basic overview for each
type, its options, and configuration.

The Unidirectional Pipe Prover

The Bidirectional Pipe Prover

The Compact Prover

The Master Meter
