Air Flow Measurement Instruments
Air Flow Measurement Instruments
LUGB vortex flowmeter air flow measurement instruments is widely used in the measurement of liquid or gas flow in industrial pipelines such as petroleum, chemical, electric power and light industry. Since the sensor material is 1Cr18Ni9Ti, it can also be used for urban water supply, heating, boiler water supply, and flow measurement of fluid pipelines in the medical industry.
Explosion-proof vortex flow sensor uses intrinsically safe explosion-proof technology. The battery-powered vortex flowmeter has the explosion-proof mark “Ex iaIIBT4”, which is suitable for use in hazardous areas of Zone 0, Zone 1 and Zone 2 containing Class II B, including T1~T4; The explosion-proof mark of the flowmeter is “ExiaIIBT5”, which is suitable for use in hazardous areas of Zones I, 1 and 2 with Class B and Class B and T1~T5
