Submersible Level Transmitter

Product Image

Submersible level transmitters are widely used in industries that require accurate and reliable measurements of liquid levels in tanks, wells, and other submerged applications. These transmitters are designed to withstand immersion in liquids and provide continuous level monitoring. In this guide, we will explore the working principles, features, applications, and benefits of submersible level transmitters.

Working Principle

Submersible level transmitters operate based on the hydrostatic pressure principle. They consist of a sensing element, typically a pressure sensor, encased in a waterproof housing. The transmitter is submerged in the liquid, and the pressure exerted by the liquid column above the sensor is directly proportional to the liquid level. This pressure is converted into an electrical signal that represents the liquid level, which can then be measured and displayed.
