A tank prover is a volumetric vessel that has a reduced cross section or neck located at both the too and bottom or, in the same cases, at the top only.

This necks are equipped with gauge glasses and graduated scales.

Tank prover may be opened to the atmosphere, or they may be closed pressurized vessels.

Proving by a tank prover employs the standing start-and-stop method (that is, the flow through the meter must come to a complete stop at the beginning and end of each proving run.)
