Turbine metering stations calibration frequency
(OP)
Pipeline delivering sites are usually provided with turbine meters to quantify the shipped commodities. A cheap method to check such meters is by means of one master meter prover, which is another turbine kept well-preserved since normally unused.
Please advise about both meters and master meter prover standard calibration frequency.

RE: Turbine metering stations calibration frequency
As a general point, master meters are typically used in the Petrochemical Industry in conjunction with a reliable secondary standard, Vol tank or displacement prover. This allows them to be checked on the actual fluid before comparison with the service meter. Where only a master meter is used, this is really only a "check" not a proving. You should bear in mind that all meters deviate for various reasons, wear, damage, viscosty effects etc.So actual cal in situ on the process fluid at operating conditions, provides a much more complete picture than a "check" meter.Don't assume master meter installations or services are necessarily "cheap", they can be very disruptive to normal operations & "good" rigs are fairly expensive to hire.
