GRA-type Gas Rotary Flowmeter

Main Functions

Configured with volume corrector to achieve the following fuctions:
● Configured with volume corrector, to have the correction of temperature, pressure and compressibility factor and convert volume at measurement condition into volume at reference condition;
● Configured with volume corrector, it could additionally transfer the data on site to the data center via GPRS/CDMA;
●Configured with flow compensation controller, it can achieve prepayment function.
