The device is installed at the bottom of the relay box, the input part is the balance cover, and the two are connected by the guide pipe (pressure). The pressure of the liquid column is indirectly transferred from the guide pipe to the part through the air conduction, so as to avoid direct contact between the device and the medium under test. The balance cover type liquid level transmitter is not only suitable for the measurement of ordinary water, but also suitable for the measurement of liquid level in high temperature, viscous, corrosive and other special occasions. It is widely used in the fields of chemical industry, metallurgy, power station, water benefit, urban water supply and industrial wastewater.

Main technical parameters: measuring range: 0-1 ~ 30m measuring medium: all kinds of water, heavy and light oil, crude oil, acid and alkali and other corrosive liquids precision: 0.25%F·S; 0.5% f. S output normally 0.5% f. (S) : 4 ~ 20 madc temperature: 0 ~ 60 ℃ environment temperature, medium temperature 0 ~ 250 ℃ power: 24 VDC dustproof moistureproof: all-weather level of explosion-proof: EXia Ⅱ CT5 instructions header: 100% pointer header or 3 1/2 a liquid crystal display (when you place an order, please specify)

Balance bell type liquid level transmitter working principle: when the balance of the transducer into a position in the liquid, after airway pressure sensor for: P = 9.807 pH + Po which feel the pressure, P - sensor unit kPa P - level density, g/cm3 H - liquid level height, under test unit m Po - on the surface of the liquid pressure, if unit kPa sensor on the back of the cavity and the fluid surface connected, the Po is zero, so H is approximately equal to 0.102 P/P, the transmitter converts the signal of stress signal, the signal is proportional to the height of liquid surface.

Note: the container of the liquid to be measured must be open to the atmosphere and cannot be closed, otherwise the measurement results are meaningless.
