Master Meter is a dedicated P.D.meter used to calibrate other meters.

These meters are typically used by the petrochemical industry for the calibration of PD meters in truck loading bays, pipeline meters for the transfer of products from refineries to terminal and the calibration of tank truck meters.

Master Meter can be mounted on trolley with all necessary equipment to be connected to other P. D. meters for calibration.
Until now the usual way of proving positive displacement meters is by means proving tanks With the Master Meter the calibration operation time is reduced by half using a single operator/calibration engineer to carry out the meter calibration.
