20m Oil Diesel Fuel Measuring Instrument,RS485 4-20mA Water Tank Level Sensor

Submersible level transmitter , based on the principle that, the hydro static pressure of measured level is proportional to the height of this liquid , adopts the piezoresistive effect of diffused silicon , converts pressure into electrical signal, by temperature compensation and linear calibration , then converts into standard current , voltage and RS485 signals and outputs .
It can be directly connected with PLC/DCS ,display instrument and computer , remote signal transmission also can be carried out. The level transmitter is widely used in liquids measurement of petrochemical , water supply and drainage , environmental protection and electric power…
