The Submersible Level Transmitter is manufactured with an advanced isolated diffused silicon sensing element. By directly immersing the probe into the liquid, it accurately measures the height from the sensor tip to the liquid surface.
The measured hydrostatic pressure signal is processed by internal signal conditioning circuits and converted into standard current, voltage, or RS485 output signals, establishing a linear relationship between output signal and liquid depth.
With reliable performance and simple installation, the transmitter is widely used for level measurement and control in industries such as oil & gas, chemical processing, power plants, municipal water supply, and hydrological monitoring.
High-performance diffused silicon pressure sensor with excellent stability and high accuracy
Submersible probe design for direct immersion, easy and convenient installation
Multi-level protective structure for enhanced durability and environmental resistance
Multiple models available to meet various industrial application requirements
The submersible level transmitter operates based on the principle that the static pressure of a liquid is proportional to its height.
Using the piezoresistive effect of a diffused silicon pressure sensor, the hydrostatic pressure generated by the liquid column is converted into an electrical signal. After temperature compensation and linear correction, the signal is transformed into standard 4–20 mA, voltage, or RS485 output, enabling accurate and stable liquid level measurement.
The submersible level transmitter is suitable for continuous liquid level measurement and control in various industries, including:
Oil & Gas Industry
Liquid level monitoring in storage tanks, process vessels, and auxiliary systems
Chemical Industry
Level measurement for chemical liquids compatible with sensor materials
Power Plants
Water level monitoring in cooling systems, water treatment units, and auxiliary equipment
Municipal Water Supply
Monitoring water levels in reservoirs, water towers, and pumping stations
Hydrological Monitoring
River, lake, groundwater, and well water level measurement
Industrial Tanks & Containers
Liquid level measurement in open or closed tanks and vessels
