fcm-type volume corrector
it’s a high accuracy intelligent secondary instrument which can support the gas turbine flowmeter, gas rotary(roots) flowmeter, gas precession flowmeter, gas vortex flowmeter and diaphragm meter with pulse signal output.
it adopts high-accurate digital temperature transducer and digital pressure transducer; it can not only detect and display the local pressure and temperature, but aslo convert the volume flow and total volume of the meter at measurement condition into the volume flow and total flow at base condition based on the detected medium temperature and pressure value; in addition, with a variety of signal output interface, it can be easily networked with other secondary instruments or computer system to form a network management system.
the key technologies of this product reach the domestic advanced level and it’s an ideal supporting instrument for gas flowmeter in city gas, petroleum, chemical industry and metallurgy industry, etc.
