1.Product description
The radar water level gauge is based onelectromagnetic wave ranging technology for accurate time measurement. The sensor emits
electromagnetic waves to illuminate the water surface and receivesits echoes, thereby obtaining information such as the distance from the
water surface to the electromagnetic wave emission point, the rate of change of the distance (radial velocity), the azimuth, and the height.
The radar water level gauge is aninnovative application of industrial ranging radar in the field of water level measurement. It realizes the
technology of water level gauge to high precision(millimeter), large range (70 meters), high reliability, easy installation andmaintenance-free technology.The radar water level gauge is connected to a computer, PLC, etc. through a standard signal interface,and can also be
connected to a corresponding display, recording, and controldevice (such as RTU) to form a water level monitoring system.
The radar water level gauge is applicable to the water level of the rivers and reservoirs, the water level of the open channel, the front of the reservoir dam, the water level monitoring under the dam, and can also be used for water conservancy and hydrology occasions such as
mountain torrents, flood control, and pressure tower (well) water level monitoring.
