top radar level measurement factory for detecting

Characteristics of water conservancy industry application:

Ø  Radar level meter adopts a recommended industry emission frequency of 26GHz, so it has beam angle is small, concentrated energy, has stronger anti-interference ability and greatly improves the precision and reliability of measurement.

Ø  Small antenna size, easy to install and dustproof cover antenna protection device.

Ø  Light weight about 1KG, easy to install.

Ø  The measurement range of up to 70 meters, covering a large reservoir water level measurement.

Ø  With a variety of output circuit interface and data acquisition system.

Ø  The pulse working mode, radar level meter transmit power is very low, no harm to human body and environment.

1.   Installation

l  Preparation before installation:

Ø  Please pay attention to the following matters, to ensure that the instrument can be installed correctly:

Ø  Please reserve enough space for installation.

Ø  Please avoid installing occasions strong vibration.

l  Illustration and installation position

Note: Radar antenna microwave pulse, have a certain emission angle. From the lower end of the antenna to be measured between the surface of the medium, and a transmitter shall be no obstruction in the region of the microwave beam radiation. Therefore, the installation should be avoided as far as possible shelter facilities, shall be carried out "false echo study" when necessary. Also note that when installing devices: the highest level measured shall enter blind; instrument must be connected to the earth, increasing the lightning protection measures; outdoor shade should be taken, rain measures.
