Product Overview
Integrated electronic water level gauge is a digital water level sensor that uses a microprocessor chip as the controller and built-in communication circuit, with high reliability and anti-interference performance. Suitable for water level measurement in areas such as road waterlogging, rivers, lakes, reservoirs, and water channels.
The integrated electronic water gauge adopts production technology, using stainless steel material as the protective material for the shell, and internally treated with high-performance sealing materials. The product has the characteristics of corrosion resistance, frost resistance, heat resistance, and aging resistance. It can be used in various harsh environments in water conservancy and hydrological surveys. The electronic water level measurement sensor for road waterlogging has the characteristic that the sampling accuracy is independent of the length of the sensor's measuring body, and the measurement accuracy remains unchanged for different amplitude application environments.
The integrated electronic water level gauge is a high-performance water level measurement device that integrates water level sensors, lithium batteries, and 4G wireless communication. It realizes continuous automatic monitoring of water level data and automatically reports it to the information management center at pre-set time intervals.
