Radar Non Contact Water Level Sensor for water level monitoring installation

Radar Non Contact Water Level Sensor is a high-precision non-contact water level measuring instrument, no logging is required. It is easy to install and can directly measure the water level of natural rivers.

Radar Non Contact Water Level Sensor field comparison test application test, analyze the accumulated measurement data and comparison test results. In order to expand the test results, provide a basis for the selection of water level gauges, and at the same time improve the water level measurement and reporting conditions of the hydrological station on the upper reaches of the Yellow River.

Let me introduce to you the installation diagram of Radar Non Contact Water Level Sensor.

Preparation and inspection before installation;

Please pay attention to the following matters to ensure that the meter can be installed correctly;

Please reserve enough space for installation;

Please avoid installation situations with strong vibration;

Please see the installation diagram description and installation location of the radar water level gauge below:

When a radar antenna emits microwave pulses, it has a certain emission angle.

There should be no obstacles from the lower edge of the antenna to the surface of the measured medium, and in the area radiated by the microwave beam.

Therefore, shielding facilities should be avoided as much as possible during installation, and “false echo learning” must be carried out when necessary.

Also pay attention when installing the instrument: the highest liquid level must not enter the measurement blind zone. The meter must be connected to the ground, and lightning protection measures should be added. Outdoor shading and rainproof measures should be taken.

If you need to measure river water level, open channel level, etc. The Ultrasonic Liquid Level Sensor can be used for non-contact continuous level monitoring.

Non contact type water level sensor

Non contact level sensor is when the liquid level gauge measures the liquid level, the sensor does not need to touch the measured medium.

Common non contact level sensors include ultrasonic and radar.

Ultrasonic Level Sensing sensors and transmitters are used for continuous, non-contact level measurement.

Ultrasonic Level Sensing

Ultrasonic Level Sensing is a low-cost liquid level measurement technology. Ultrasonic Level Sensing sensors and transmitters are used for tank or river level measurement. Ultrasonic Level Sensing does not need to contact the medium, can be continuously measured, low cost. Therefore, Ultrasonic Level Sensing is very popular among users. Ultrasonic liquid level sensors are available in general and intrinsically safe types. Output 4~20mA standard signal or output the measurement result to the secondary meter through RS-485. Meets the system’s automatic control.

Radar level measurement uses Non-contacting radar technology for Continuous level measurement. Liquids and solids are commonly measured with this measuring technique.

Non-Contacting Radar Level Measurement

Radar level transmitters use radar technology to perform non-contact continuous level measurement. The radar level indicator converts the level into an electrical signal. The level signal output can then be utilised by other instrumentation to monitor or control. Liquids and solids are commonly measured with this measuring technique. Like: Fly ash silo. Radar level sensors are divided into: Pulsed radar technology and frequency modulated continuous wave (FMCW) radar level sensors.
