To ensure that a gantry meter is reading accurately and to comply with regulations, it is necessary to carry out periodically a test or series of tests in which the meter's readings are compared with proving equipment that is traceable to national standards. A primary objective of this publication is to promote uniformity and consistency both in the proving of gantry meters and in the interpretation of the results.
This publication describes procedures applicable to turbine gantry meters (road and rail) and proved by reference meter or volumetric proving tank. Many of the procedures are identical to those employed for proving positive displacement meters, but where turbine meters require particular attention, the details are given.
