Displacer Level Transmitter

Displacer Level Transmitter

Displacer level transmitter is applicable to measure the liquid level or interface at condition of high temperature or high pressure.

Principle:

The displacer immersed in the liquid is subjected to downwards gravity, upwards buoyancy and upwards spring force, when the three forces reach 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 a new balance. The extension and retraction of the spring makes the torque tube produce angle movement, through magnetic coupling which drives transmission gear to indicate liquid level.
