Characteristics of High Frequency Radar Level Meters
1. Multiple horn and flange forms to choose from, suitable for measuring solid particles and dust under various complex working conditions;
2. By adopting advanced microprocessors and unique echo processing technology, the radar level meter not only enhances the echo capability but also helps to avoid interfering objects. It can be applied to various complex working conditions;
3. Adopting a high-frequency transmission frequency of 26GHz, the beam angle is small, the energy is concentrated, and it has stronger anti-interference ability, greatly improving measurement accuracy and reliability;
4. The antenna size is small, easy to install, with multiple sizes to choose from, suitable for different range ranges;
5. Shorter wavelengths have better effects on tilted solid surfaces;
6. The measurement blind spot is smaller, and good results can also be achieved for small tank measurements;
7. Almost not affected by corrosion and foam;
8. Almost unaffected by changes in water vapor, temperature, and pressure in the atmosphere;
9. Severe dust environments will not affect electromagnetic operation;
10. High signal-to-noise ratio enables better performance even in fluctuating environments.

Working principle:
Measurement principle: Micro power microwave pulses are emitted from radar antennas, propagated at the speed of light in space, reflected back by the measured object, and received by the radar. The time difference between the transmission and reception of pulse signals is proportional to the distance from the radar antenna to the measured object. The propagation speed of electromagnetic wave signals in space is usually measured at the speed of light. When measuring distance, the time difference between transmitting and receiving pulses is extremely short, only on the nanosecond level. Conventional techniques are difficult to accurately measure this time. The CX-RLM series high-frequency radar level instrument adopts advanced equivalent sampling methods to accurately measure the originally nanosecond time interval, thereby achieving accurate distance measurement.
Transmit Reflect Receive: An extremely small 26GHz radar signal emitted in the form of short pulses from the antenna end of a radar level meter. Radar pulses are reflected by the sensor environment and object surface and received by the antenna in the form of radar echoes. The rotation period of radar pulses from transmission to reception is proportional to the distance, i.e. the level of the object.
Input
The antenna receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes this signal to identify the echo generated by the microwave pulse on the surface of the material. The correct recognition of echo signals is completed by intelligent software, with an accuracy of up to millimeter level.
Output
By inputting the empty tank height E (=zero), full tank height F (=full range), and some application parameters, the application parameters will automatically adapt the instrument to the measurement environment, corresponding to (4-20) mA output.
Advantages of radar level gauge
Radar level gauges have multiple advantages, making them the preferred choice in many applications.
Non contact measurement: Radar level gauges can be measured without the need for liquid contact, greatly reducing maintenance and cleaning requirements.
Large height range: Radar level gauges can measure large liquid levels, even up to tens of meters.
High accuracy: Due to the use of advanced microwave radar technology, the measurement accuracy is usually at the centimeter or even millimeter level.
Strong anti-interference ability: radar level gauge has strong resistance to other interference factors in the environment (such as steam, foam, etc.).
Real time monitoring: The radar level gauge can monitor changes in liquid level in real time, providing operators with timely and accurate information.
Strong reliability: Due to its non-contact design and resistance to harsh environments, radar level gauges have high reliability.
Long lifespan: Due to its working principle and design, radar level gauges have a longer service life.
Application of radar level gauge
With the continuous development of industrial automation and process control technology, the application of radar level gauges in the market is becoming increasingly widespread. In the petrochemical industry, radar level gauges are used to monitor the oil level in oil tanks; In the food processing industry, radar level gauges are used to monitor liquid food in storage tanks; In the pharmaceutical industry, radar level gauges are used to monitor the storage status of pharmaceutical liquids. In addition, radar level gauges are widely used in other fields that require precise level measurement, such as water treatment, chemical industry, pharmaceuticals, etc.
