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
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.
