Difference between radar level gauge and guided wave radar level gauge
The antenna of the radar sensor of the radar level gauge transmits the electromagnetic wave signal in the form of Beam, and the transmitted wave reflects on the surface of the measured material, and the returned echo signal is still received by the antenna. Every point in the transmitting and reflecting beam is collected by ultrasonic sampling. After the signal is processed by the intelligent processor, the distance between the medium and the probe is obtained.
The radar level gauge has remarkable effect under the bad condition. It can be used to measure whether it is toxic medium, corrosive medium, solid, liquid, dust or slurry medium.
Guided-wave radar level meter is a measuring instrument based on the principle of time travel. The radar wave travels at the speed of light. The probe sends out a high frequency pulse and propagates along the cable probe. When the pulse meets the material surface, it is reflected and received by the receiver in the instrument, and the distance signal is converted into the level signal.
Guided-wave radar level gauge has a strong ability to suppress steam and foam, the measurement is not affected by liquid density, the porosity of solid materials, temperature, dust during feeding, low maintenance, high performance, high precision and high reliability, long Service Life.
