Eastern Petroleum Supplies Manufactured Master Meters

Still the usual way of ‚Äčtesting positive displacement meters accuracy is by means of proving tanks, specially designed and built tanks of known capacity. These methods, when carefully conducted by skilled operators, can be accurate, but they lay themselves open to many errors. They are also slow and the equipment is cumbersome.

The Master Meter system has been designed to simplify the whole procedure of checking the accuracy of a meter. In many applications this can be done with the meter under test in its normal operating position, and the equipment is easily transportable.

It cannot be emphasized too strongly that with modern meters, repeatability is such, that it should be possible to carry out a number of runs at the same speed and obtain consistent results. No meter, including a Master Meter, is accurate, throughout its speed range, but provided it is consistent, and the variation is known, at any given speed of reading of the Master Meter may be corrected by the application of a factor. By using the electronic counter with the linearization of the error curve, the Master Meter error is very near to zero.

The Master Meter consists of a standard series P.D. Meter (mounted in a Carry Frame, mobile trolley, Road Going Trailer or Skid Base). The direction of flow through the meter is indicated by arrows on the meter manifold.
