Self counting water level recorderIt is a hydrological monitoring device that can automatically and continuously collect and store water level data, widely used in hydrological stations, groundwater monitoring wells, reservoirs, rivers, laboratory simulated hydrological experiments, and other scenarios. It can replace manual timed measurement and achieve unmanned tracking of water level changes. Data can be obtained through local reading or remote transmission.

　　Self counting water level recorderWorking based on the principle that water pressure is proportional to water depth. Its core components include a piezoresistive sensor and a microcontroller processing unit. The water pressure signal is converted into a voltage signal through a solid-state piezoresistive sensor, and after analog-to-digital conversion, the data is processed by the microcontroller. Some devices are also equipped with wave suppression algorithms and pre-set elevation parameters to reduce water surface wave interference and ensure measurement accuracy.

Function:

Automatic continuous recording: capable of long-term and continuous recording of water level changes without manual intervention.

Data remote transmission and display: Some devices support the remote transmission of recorded water level data in digital or image form indoors for real-time monitoring and data analysis.

High precision measurement: The measurement accuracy error usually does not exceed ± 3cm, meeting the high-precision requirements of hydrological monitoring and industrial liquid level measurement.

Wave suppression and data processing: equipped with wave suppression algorithms to reduce the impact of water surface fluctuations on measurement results; Support data sampling, terminal display, and printing recording functions.

Selection considerations:

Measurement object: Consider the physical and chemical properties of the measured medium, working pressure and temperature, installation conditions, liquid level change rate, etc.

Measurement and control requirements: Clearly define the measurement range, measurement accuracy, interface with computers, safety and corrosion prevention, reliability, and construction convenience requirements.
