3 Prover

3.1 Types of prover

The following types of proving systems are in use:

a) tank prover systems: made of metal (stainless steel, carbon steel, etc.), of the specified structure, with certain volume, and may be used as a means of standardization of transfer

b) pipe provers: bidirectional and unidirectional. Pipe provers with precision tubes as described in 6.7 are available for special applications.

c) master meters: a meter is used as a means of standardization of transfer. Master meters shall be verified as qualified under the condition close to the actual working condition, and then the working meter shall be verified by volume comparison method. This method may produce additional errors.

3.2 Setting of provers

Provers may be used either connected (fixed or mobile) to the metering station or in a central proving station to which the meters or the measures can be taken to be proved unconnected.

3.3 Minimum pulses

In order to limit the maximum error to ±0.01% when using a pulse generator for proving, at least 10000 pulses shall be obtained from the meter per proving run. This number of pulses may be reduced by pulse-interpolation techniques which allow either the use of meters with fewer pulses per unit volume or reduction of the prover volume.
