Tips: Application of radar level sensor in reservoir water level monitoring
The reservoir water and rain monitoring system is suitable for the water conservancy management department to remotely monitor the real-time data such as the water level and rainfall of the reservoir. It also supports remote image monitoring, providing accurate and timely on-site information to ensure the appropriate water storage of the reservoir and safe flood season.
The reservoir water and rain monitoring system has achieved real-time monitoring of the water and rain conditions of the reservoir, realized the information management of the reservoir, and played a major role in protecting people's lives and property safety.
System composition:
Radar level sensors, rain gauges, reservoir detection terminals, security cameras, communication devices, etc.
Functions:
- Remote detection
- Reservoir distribution location and on-site equipment operation status.
- Real-time data such as water level, rainfall, device battery voltage, etc.
- Remote monitoring
- During GPRS/CDMA communication, it supports timed, over-limit or remote manual photography.
- Support video real-time monitoring during optical fiber/ADSL/3G/4G communications.
- Automatic alarm
- When the water level/rainfall exceeds the limit or the field equipment fails, it will automatically alarm.
- Automatically send alarm text messages to the responsible person's mobile phone.
- Statistical Analysis
- Automatically count the time, day, month and year data reports of water level and rainfall.
- Automatically generate process analysis curves such as water level, rainfall, and battery voltage.
- Data storage
- Two-way storage of historical data between monitoring center server and field terminal.
- Field terminals can store historical data records of no less than one year.
Radar water level sensor using advanced non-contact radar measurement technology has measuring range from 0-10m, 0-30m, 0-50m, 0-60m to 0-70m, optional output signal 4-20mA, HART, RS485/232 and optional power supply DC 12-24V, AC 220V. Radar level transmitter consists of protection head with LCD display, waterproof connectors, internal radar antenna, horn and installation accessory, can be used for measuring liquid level of reservoir/ river/ lake/ water tank.
