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.
- A dedicated instrument for gas measurement
- A dedicated instrument for oil & gas recycle system
- High accuracy: ±1.5%, ±1.0% or ±0.75%
- Good repetitiveness
- Test temperature, pressure, and flow of measured gas; automatic tracking and compensation of flow; an indication of gas total volume under standard status; real-time query of temperature, pressure, time and date, etc.
- Built-in pressure & temperature sensor, high safety performance, compact structure & beautiful outlook
- Low power consumption, more than 3 years service life for one 3V 10AH lithium cell
- Instrument factor, total flow value kept for 10 years after power off
