Validating New Gas Metering Skid


Thread Starter



Can one provide us with more information on validating procedures for the new gas metering system (Natural Gas for Custody Transfer).

We are using SICK 4 path ultrasonic meter, with Omni flow computers. We have come out with standard test procedure to validate Flow Meter and Flow Computer. i.e for Ultrasonic Meter to do SOS check between measured and computed, Check on profile factor and Velocity of Gas.

For Flow computer we have planned to 48 hours validation check on hourly averages between pay and check meters.

It would be of great help if some one has more information on this ?

Hi Saran:
For which company are u working with? Have you done the proving test with a master meter?
