Underground water level and water temperature measuring instrument

Product Principles

The WH311 groundwater level gauge adopts the principle of laser static pressure: based on the principle of static water pressure, which is proportional to the water depth, the water level gauge is made using WHSENSORS intelligent chip components. When the sensor is fixed at a certain point underwater, the pressure of the water column above that measuring point acts on the sensor, causing a change in the resistance of the component, resulting in a voltage change. This indirectly measures the water level at that point. The WHSENSORS liquid level sensor of Dongfang Wanhe Instrument adopts laser calibration zero point, which effectively improves the accuracy of liquid level measurement at full range, with some ranges up to 1 centimeter.

A certain plateau area requires long-term monitoring of the temperature and water level of high-temperature geothermal wells. The water depth and water level sensors are used to collect changes in the level and temperature of geothermal wells, which are installed underground. The monitoring station is equipped with a liquid level and temperature integrated display. With the help of a 24V power supply, a paperless recorder is used to store and send the collected data, achieving the functions of saving and querying data such as liquid level and temperature. Support users to retrieve data for autonomous applications.
