Master Meters are high-precision meters that speed up calibration operations as they can be placed in series with the meter to be calibrated, thus conveying the product to a recovery line or tank.

Master Meters can be mounted on trolleys with wheels so that they can also be transported by road to get as close as possible to the meter to be calibrated. For a high level of flexibility, they can also be equipped with additional instrumentation (thermometers, pressure switches) and hoses.
