JCWQ series gas turbine flowmeter is widely used for measurement of natural gas, coal gas, liquefied gas and light hydrocarbon gas, etc.
Feature
■ Dedicated instrument for gas measurement
■ 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; 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
