METHOD FOR CHECKING MEANS OF NATURAL GAS FLOW RATE METERING DEVICES

摘要

Method for check of means for measurement of flow rate of natural gas in which natural gas is in sequence passed through means for measurement of flow rate of natural gas and standard that is block of connected in parallel nozzles of cryingal flow out. Source of natural gas is main pipeline with pressure of natural gas 36...46 bar, and receiver of gas pipeline are gas supply systems with pressures of natural gas 3; 6 or 12 bar (with stable pressures).
