YPL displacement type Level Transmitter is designed to sense Liquid level, Interface and Specific gravity. The output of the Instrument is proportional and is designed to measure and transmit electrical signal proportional to changes in Liquid level or Specific Gravity.
Principal Of Operation
The YPL series measures changes in Liquid Level, Specific Gravity or Interface Level and transmits a current output signal proportional to the change in the process parameter. The change in the process parameter causes a change in the displacer position, which is transferred to the Torque Tube producing a Rotary motion. This rotary motion is transferred through bellow to lever assembly that is supported by flexure strips.
Magnets attached to the lever assembly move past a hall effect position sensor that converts the magnetic field signal to an electrical 4- 20mAsignal.

Frequently Asked Questions (FAQs)
A displacement type level transmitter is a liquid level measurement device that provides continuous and precise level monitoring in tanks, vessels, and industrial process systems by utilizing the buoyancy principle.
Archimedes’ Principle governs how the transmitter functions. The buoyant force acting on the displacer varies as the liquid level does. For level monitoring and control, this movement is transformed into an electrical output signal, usually 4–20 mA.
- Excellent precision and dependability
- Constant level monitoring
- Appropriate for situations involving high temperatures and pressure
