LUZX precession vortex flowmeter is a new type of gas flow instrument. This flowmeter integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature, pressure, and compression factor. It is an ideal instrument for gas measurement in industries such as petroleum, chemical, power, and metallurgy. No mechanical movable parts, less prone to corrosion, stable and reliable, long service life, long-term operation without special maintenance; The intelligent flowmeter integrates flow probes, microprocessors, pressure and temperature sensors, and adopts a built-in combination to make the structure more compact. It can directly measure the flow, pressure, and temperature of fluids, and automatically track and compensate for compression factor correction in real-time.
