Deep Well Water Level Sensor | Up to 200~2000mH2O

Deep Well Water Level Sensor

Deep well water level sensor is a submersible liquid level transmitter independently designed for deep well measurement applications. Deep well water level sensor has a larger customized range and better price than ultrasonic well depth sensor! Widely used in deep well liquid level measurement, groundwater level monitoring, geothermal well measurement, etc.

  • Liquid level range: 0~200~500~1000~2000mH2O
  • Temperature range: -40~100℃
  • Output: 4~20mA, 4~12~20mA, RS485
  • Power supply: 9~36VDC


Our Deep Well Water Level Sensor product uses an OEM pressure sensor with a stainless steel isolation diaphragm as the signal measurement element. Internal sealing treatment, double isolation cavity design.

After automatic computer testing, the zero point and sensitivity temperature compensation over a wide temperature range were carried out using laser trimming technology.

It has anti-interference, small temperature drift, high stability and high measurement accuracy. It is an ideal liquid level measurement instrument in the field of deep well measurement.

  • Adopt diffused silicon pressure sensitive element diaphragm isolation technology;
  • Cable connection, directly put into use, easy to install;
  • Customers can assemble the cables themselves;
  • Anti-clogging and anti-scaling;
  • Anti-lightning strike, cut-off interference design, strong anti-interference ability;
  • Wiring reverse and overvoltage protection, current limiting protection;
  • Good stability, anti-condensation and anti-liquid filling;
  • Small temperature drift coefficient and high accuracy;

Measurement principle

Well water level sensor The pressure formula on the liquid surface is: Ρ=ρgh + P1

In the formula:

  • P: The pressure on the liquid surface of the sensor (for ease of understanding, hereafter collectively referred to as pressure)
  • ρ: Density of the measured liquid (default is 1g/cm³ during debugging)
  • g: Gravity acceleration (default is 9.8m/s² during debugging)
  • P1: Intra-cavity pressure during packaging (≈101.3kPa)
  • h: Depth of the sensor into the liquid
Well water level sensor application

Build water well monitoring system

The water well monitoring system is divided into two parts: groundwater on-site real-time monitoring equipment and monitoring center display instruments.

Well water level sensor can measure groundwater levels in various working conditions such as deep geothermal wells, mines, hot spring groundwater, water collection wells, overflow wells, etc.

Real-time water level conditions are transmitted to the user’s monitoring system through signals. Generally it is PLC or liquid level recorder, liquid level controller, etc.
