Displacer level transmitter

Applicable to measure the liquid level, interface level at condition of high temperature, high pressure.


The displacer immersed in the liquid is subjected to downwards gravity, upwards buoyancy and upwards spring force, when the three forces reach to a balance, the displacer will be static at a certain position. When the liquid level changes, the buoyancy force on the displacer will be changed accordingly, and the three forces will reach to a new balance. The extention and retraction of the spring makes the torque tube produce angle movement, through magnetic coupling which drive transmission gear to indicate liquid level.
