Meter Proving & Calibration Equipment

Volumetric Prover Overview

A Small Prover Footprint With Big Business Impact

Atmospheric with a dry-bottom design, the Meter Engineers volumetric tank prover is used in the calibration of oil flow meters for fiscal, allocation or custody transfer measurements when moving from one entity to another. The flexibility and compact size of the equipment is what makes the volumetric tank so highly valued.

Depending on the volume requirements of a meter, our engineers can design the optimal vessel to achieve your specific proving needs. There is added confidence knowing all Meter Engineers volumetric tanks are built according to American Petroleum Institute Chapter 4.4 and National Institute of Standards and Technology 105-3 recommendations – an accuracy of ±0,05% or better.

Advantages of Meter Engineers Volumetric Tank Provers
