product description
The M21A radar water level gauge is based on electromagnetic wave ranging technology for precise time measurement. The sensor emits electromagnetic waves to irradiate the water surface and receives its echoes, thereby obtaining information such as the distance from the water surface to the electromagnetic wave launching point, the rate of change of distance (radial speed), azimuth, and height.
Radar water level gauge is an innovative application of industrial ranging radar in the field of water level measurement. It realizes the technical leap of water level gauge to high precision (millimeter level), large range (70 meters), high reliability, easy installation and maintenance free.
The radar water level gauge is connected to a computer, PLC, etc. through a standard signal interface, and can also be connected to the corresponding display, recording, and control device (such as RTU) to form a water level monitoring system.
Main composition and scope of application
Radar water level gauge mainly includes: transmitter, transmitting antenna, receiver, receiving antenna, signal processing and transmitting unit. There are also auxiliary equipment such as power supply equipment, data acquisition equipment, and anti-interference equipment.
The radar water level gauge is suitable for monitoring the water level of rivers and reservoirs, open channels, and in front of the reservoir dam, and the tail water level under the dam. It can also be used for water conservancy and hydrological occasions such as mountain floods, flood control, and surge tower (well) water level monitoring.
Installation method
1. The installation of the water level gauge must have a solid foundation. It can be a vertical pole, the distance between the straight wall and the embankment is greater than 20CM, and the slope of the embankment should ensure that the antenna is located above the main stream;
2. The antenna port of the water level gauge should be installed in the waterway area without interference;
3. The horn antenna of the water level gauge needs to be installed perpendicular to the water surface;
4. Cable routing pipe, PVC pipe, galvanized steel pipe, etc. can be used.

Debugging steps
1. Correctly wire the installed water level gauge, please refer to 2.3 Wiring Definition;
After the wiring is completed, please lock the waterproof connector!
2. Turn on the power and set the necessary parameters:
The communication line RS485 is connected to the computer through the conversion module,
According to the communication protocol, use the debugging software to view or set the local address;
You can also view and set the address of the machine directly from the panel, using the ADDR button;
3. Connect the acquisition unit (such as RTU, PLC, etc.) for water level measurement and acquisition.
4. After debugging, please screw the upper cover!
