Water Level

The static pressure level gauge is a submersible level gauge. It is based on the principle that the static pressure of the liquid measured by the pressure sensor is proportional to the height of the liquid. It uses advanced isolated diffused silicon sensitive elements or ceramic capacitor pressure sensitive sensors to convert static pressure into electrical signals, which are then converted into standard electrical signals (generally 4-20mA/1-5VDC) after temperature compensation and linear correction. It is widely used in water level monitoring fields such as urban water supply and drainage, sewage treatment, groundwater, reservoirs, rivers, and oceans.

Air ultrasonic level meter uses the device to transmit ultrasonic pulse signals, which are reflected by obstacles. The receiving device receives the reflected signals, analyzes the time difference between the transmission and the echo, and calculates the change of the liquid (object) level in combination with the ultrasonic propagation speed. It has the function of automatic temperature compensation, non-contact measurement, high precision, simple installation and maintenance.

Uses lens antenna radar sensor, operating frequency 60GHz, and uses continuous wave measurement. It has the characteristics of corrosion resistance, high precision, low power consumption, and strong anti-interference ability. Integrated intelligent water level tracking and identification algorithm, can filter out fixed interference echoes and multipath interference, and has intelligent perception of unstable measurement errors caused by pole shaking, bridge deck shaking, water surface fluctuations, etc., and performs intelligent optimization compensation, and the measurement results are accurate and reliable.

A dual-level mutual calibration water level measurement system (dual-channel full-range level gauge) developed based on the independent intellectual property calculation model. The dual-channel design ensures that there are no blind spots in various working conditions, and can also achieve accurate measurement under harsh working conditions (such as uneven density, surface debris, etc.). The intelligent algorithm has the functions of automatic identification and switching and elimination of abnormal data, and real-time dual-level mutual calibration. When a value jumps or abnormal values appear, the system automatically calculates to ensure data accuracy. The equipment uses static pressure and ultrasonic data as backup to ensure the online rate of the equipment.

It has the characteristics of corrosion resistance, high precision, low power consumption, strong anti-interference ability, etc. Integrated intelligent water level tracking and identification algorithm, can filter out fixed interference echo, multipath interference, intelligent perception of pole shaking, bridge deck shaking, water surface fluctuations and other causes of unstable measurement errors, and intelligent optimization compensation, the measurement results are accurate and reliable. Suitable for manholes, sewers, storage tanks and other scenes.

The buried waterlogging monitor is based on the principle of underwater ultrasonic level measurement. It uses the time difference between the emission of sound waves and the reception of the water surface echo to obtain the current liquid level height, realizes water immersion detection and liquid level collection, and monitors the waterlogging situation on the road. It consists of a stainless steel shell, a water level detection module, a Bluetooth module, a GPRS/4G/NB-IoT/LORA wireless communication module, a battery, etc. Developed based on the characteristics of urban waterlogging, it has a compact size and can be buried in the road surface to achieve waterlogging monitoring.
