IS 15676 : 2006 Flow Measurement of Natural Gas By Turbine Meters
| ICS 75.160.30;75.180.30 | PGD 26 |
|
| Reaffirmed 2022 |
1 Scope
This standard specifies the requirements of dimensions,ranges, construction, performance, calibrati-on andoutput characteristics of turbine meters for gas flowmeasurement for custody transfer.
It also specifies installation conditions, leakage testingand pressure testing and provides a series of informativeAnnexes A to E including recommendations for use,field checks and perturbations of the fluid flowing.
This standard does not cover tie equipment used inthe determinations of the pressures, temperatures,densities and other variable that rtiust be known for theaccurate determination of measured gas quantities.
In cases where conflict exists between mandatoryregulations and this standard, the former shall prevail.
