Level Transmitter

A submersible level transmitter is an industrial device that measures liquid level by directly immersing the sensor probe into the medium. It operates based on the principle that hydrostatic pressure is proportional to liquid depth. The transmitter typically uses a high-stability diffused silicon or ceramic pressure sensing element to convert liquid level into standard output signals such as 4–20mA or 0–10V. With its compact design and easy installation, it is suitable for level monitoring in tanks, reservoirs, wells, sewage systems, and various corrosive or non-corrosive liquids. It is widely used in water treatment, chemical processing, environmental monitoring, and industrial automation systems.
