Water Level Sensor Hydrostatic Submersible Liquid Level Sensor Water Tank Level Indicator

Water Level Sensor Hydrostatic Submersible Liquid Level Sensor Water Tank Level Indicator


Our water level sensor features a protective cap at the front end, designed to shield the sensor diaphragm

while allowing liquids to flow smoothly into contact with it. The waterproof cable and housing are sealed

for a secure connection, enabling long-term underwater use. The sensor includes a built-in micro signal

processing circuit, supporting remote transmission. Our liquid level sensor offers excellent stability and

reliability. It is developed using imported diffused silicon chips and low-power ADI professional chips,

combined with microprocessor technology. The sensor is compact, highly accurate, and has a

measurement range from 0m to 99m, with other ranges available for customization.


level sensor features

  • Reverse polarity protection and transient overcurrent/overvoltage protection, compliant with EMI protection standards.
    High-quality vented cable designed for long-term immersion in water.
  • Strong overload and anti-interference capabilities, offering cost-effective stability.
  • Core auto-calibration algorithm effectively prevents value fluctuations caused by water surface movement.
  • Sloped liquid inlet design effectively prevents silt and debris entry while resisting impact.
  • Submersible probe measurement method for easy and convenient installation.
  • Multi-layer protective structure design with an IP68 protection rating. Made of corrosion-resistant stainless steel, suitable for various applications.

How does a water level sensor work?

The working principle of the water level sensor is based on the relationship between liquid hydrostatic pressure and liquid level (P = ρgH). It converts the hydrostatic pressure into an electrical signal to measure the liquid level. The cable of the water level sensor contains a vent tube connected to the external atmosphere, which measures both underwater pressure and atmospheric pressure. The water depth is then calculated based on the pressure difference.

This liquid level sensor, when connect with a monitoing host, can control the switching of water pumps and solenoid valves based on water level data set by the administrator, enabling remote automatic control.
