JCWQ Turbine Gas Flow Meter 

JCWQ series gas turbine flowmeter is widely used for the measurement of natural gas, coal gas, liquefied gas, and light hydrocarbon gas, etc.

Turbine gas flow meters are an ideal instrument to measure gas flow, especially for the clean, low viscosity gas fluid. JCWQ gas turbine flowmeter can measure volumetric flow when fluid flowing past a rotor without spinning. It can also measure mass flow if the gas density is set. JCWQ turbine gas flowmeters are a favorite device for trading settlement.
