Description
LWQ-80 gas turbine flowmeter integrates the theories of gas mechanics, fluid mechanics, electromagnetism and so on to develop a new generation of gas precision metering instrument, excellent low and high pressure metering performance, a variety of signal output modes and low sensitivity to fluid disturbance are widely used in the measurement of natural gas, coal-to-gas, liquefied gas, light hydrocarbon and other gases.
LWQ gas turbine flowmeter adopts low-power single-chip microcomputer technology to develop turbine flow sensor and intelligent instrument integrated with display and calculation. It has the advantages of compact structure, intuitive and clear reading, high reliability, no interference from external power supply, anti lightning and so on. Instrument coefficient six point correction, intelligent compensation instrument coefficient nonlinear, and can be modified on site. Clear LCD displays instantaneous flow (4 significant digits) and cumulative flow (8 significant digits, with reset function). The valid data will not be lost for 10 years after power failure. Explosion proof grade: exdiibt6.
