Product Introduction
The electronic water level gauge is an integrated induction type electronic water level gauge consisting of a measuring part and a circuit conversion transmission part. The sensor measuring body uses electronic methods to locate the sensing device and sense changes in water level. After digital encoding processing, it achieves digital indexing, digital sampling, and digital transmission, making it a new type of fully digital electronic water level gauge. Through the RS485 signal interface, it can be connected to personal computers, PLCs, and corresponding display, recording, and control devices (such as RTUs) to form a water level measurement (control) system.
scope of application
It can be used for water level monitoring in rivers, lakes, reservoirs, hydropower stations, irrigation areas, water conveyance and other water conservancy projects, as well as in municipal projects such as tap water, urban sewage treatment, urban road ponding, and food chemical projects such as alcohol and beverages.
Product Features
1. Using microprocessor chips as controllers, with built-in communication circuits and lightning protection devices
2. Adopting stainless steel protective shell, it has high reliability and anti-interference performance
3. Internally treated with special sealing materials, it has the characteristics of anti-corrosion, antifreeze, heat-resistant, and anti-aging
4. Sampling accuracy is independent of length, and the measurement accuracy of sensors with different amplitudes remains unchanged (for equal precision measurement, the measurement accuracy remains unchanged for different water level amplitudes)
5. This type of sensor can be used as a single unit or in multiple cascaded units
6. Multiple pairs of water level waves have been digitally filtered to ensure the true value of the water level
