Buoy type liquid level sensor
Buoy type liquid level transmitter is to change magnetic floating ball into buoy. The liquid level sensor is designed according to Archimedes buoyancy principle. Buoy type liquid level transmitter uses tiny metal film strain sensing technology to measure liquid level, boundary or density. It can perform routine setting operation through on-site keys when it works.
Hydrostatic level sensor
The transducer works on the principle of hydrostatic pressure measurement. It usually uses silicon pressure transducer to convert the measured pressure into electrical signal, which is amplified and compensated by amplifier circuit. Finally, the transducer is output in 4-20 mA or 0-10 mA current mode.
