summary
With the rapid development of communication technology and control technology, computer monitoring system is widely used in hydropower stations, especially when the control mode of "nobody on duty and few people on duty" is put forward, hydropower stations, water conservancy projects and other projects put forward new requirements for the automation level of gate monitoring and management.
According to the market demand, our company has developed a new generation of water level measurement and control system. The system uses sensor technology and network communication technology. Applicable to any occasion and requirement.
Solution
The user can view the field data in the central control room, office or any other place with network by installing sensors and meters on the site and matching corresponding communication modules.
Water level sensor
We currently recommend two kinds of water level sensors. Users can choose one according to the site requirements, one is a throw in type level transmitter and the other is a float type water level gauge.
Float type water level gauge: this water level gauge is applicable to the environment where the water level accuracy is required to be high, or the liquid turbidity is not applicable to the throw in type liquid level transmitter.
Advantages: high precision, reliable operation and wide application;
working principle
The float type water level gauge is to float a float on the water surface by hanging a steel wire, and measure the water level by the change of the length of the steel wire caused by the rise and fall of the water surface.
Technical parameters:
Water level variation: 0-10m: 0-20M; 0-30m； 0-40m； 0-80m；
Resolution of water level encoder: 1 ㎝;
Measurement accuracy: ≤ 0.2%;
Float diameter: Φ 40mm； Φ 50mm； Φ 100mm optional;
Ambient temperature: - 10 ℃ ~ 85 ℃;
Relative humidity; < 90%(40℃).；
Output signal: RS485, 4-20mA.
