Research of The Mobile Ultrasonic Gas Flowmeter as Work Standard

摘要

Now, most gas flowmeters are taken to the special verification station to test (verify or calibrate) by manufacture in the world. It's obvious that shortcoming and wasting. The ChenDu Verification Branch(In brief CVB) imported a set of mobile gas ultrasonic measurement system for nature gas, which is much advancer of the world from the Instromet company in Holland. After the gas ultrasonic meters have been tested in CVB, the system's performance is proved that it work very well and also can meet the requirement the nation build the mobile work standard for flowmeters in the field. It inaugurate the new epoch which use the mobile gas flow verification system to test((verify or calibrate) those gas flowmeters in the field.
