A meter in a high pressure gas pipeline is calibrating using a sonic nozzle in series with the meter. A bypass line is run where measurements are made to determine gas composition dependent factors for use in defining the flow through the nozzle.

Method for determining the accuracy of a gas measurement instrument

An internal gate rotary vane fluid meter which has markedly improved performance as a result of precise control over the geometry and dimensions of the rotating elements and the fluid flow path. In particular, the outer diameter of the gate is maximized and the inlet and outlet passages of the meter are shaped to perpendicularly intersect the rotor vanes when the vanes are sealing against the respective ends of the meter crescent. Furthermore, the inlet and outlet passages each have a total cross-sectional area substantially equal to a vane area to provide substantially constant fluid velocity.

An electrical transducer connected to a computer-based system is temperature compensated by providing an assembly including the transducer, which assembly further includes a temperature transducer and a coding element providing a signal which is decoded by the computer to specify the zero shifts and sensitivity changes of the transducer at high and low temperature extremes.
