Submersible Level Transmitters

What Is a Submersible Level Transmitter?

A submersible level transmitter is a liquid level measurement device designed to measure the depth of liquids by detecting hydrostatic pressure. It is typically installed directly into water, tanks, wells, reservoirs, or other liquid containers to provide continuous and accurate level monitoring.

Unlike traditional level gauges, a submersible level transmitter can work underwater and convert the pressure generated by liquid depth into standard electrical signals, such as 4-20mA or RS485, for connection with PLC systems, control panels, and remote monitoring platforms.

SISCO submersible level transmitters are widely used for water level measurement, groundwater monitoring, reservoir monitoring, wastewater treatment, and industrial liquid level control.

How Does a Submersible Level Transmitter Work?

A submersible level transmitter works based on hydrostatic pressure measurement technology. The deeper the liquid, the greater the pressure applied to the sensor diaphragm. The transmitter measures this pressure change and converts it into an electrical output signal proportional to the liquid level.

With high accuracy options of 0.5%FS and 1.0%FS, SISCO hydrostatic level transmitters provide reliable measurement performance for continuous liquid level monitoring applications.

What Is the Measuring Range of a Submersible Level Transmitter?

SISCO submersible level sensors are available with measuring ranges from 0 to 50 meters, providing flexible solutions for different liquid level measurement applications. The measuring range can be selected according to the installation depth and liquid level requirements, making the transmitter suitable for shallow water tanks as well as deep groundwater wells, reservoirs, and industrial storage systems.

With a hydrostatic pressure measurement principle, the submersible level transmitter delivers accurate and stable level monitoring even in deep water applications. The 0–50m measuring range makes it ideal for groundwater level monitoring, reservoir water level measurement, dam monitoring, wastewater treatment, and industrial liquid level control.

Different measuring ranges and cable lengths can be customized to meet specific project requirements, ensuring reliable installation and continuous liquid level measurement in various environments.

Where Are Submersible Level Transmitters Used?

Submersible level transmitters are widely used for continuous liquid level measurement in water management, industrial automation, and environmental monitoring applications. With reliable hydrostatic pressure measurement, 4-20mA or RS485 output options, and measuring ranges up to 50 meters, they provide accurate and stable level monitoring in various liquid measurement environments.

Groundwater Wells and Groundwater Level Monitoring

Submersible level transmitters are commonly installed in groundwater wells to monitor underground water levels continuously. They help measure water table changes, support groundwater resource management, and provide reliable data for environmental monitoring and water conservation projects.
