The Guided Wave Radar Level Transmitter
The guided wave radar level meter, a common liquid level measurement device, is widely used in the industrial field for its efficient and accurate measurement performance. Compared with other types of radar level meters, guided wave radar level meters have shorter measuring distances, mainly due to their special contact measuring principle.
The uniqueness of the guided wave radar level transmitter is that the probe must be in contact with the measured liquid, which is different from the traditional non-contact measurement method. The probe of the radar level sensor is in direct contact with the liquid, and then the principle of reflection of electromagnetic waves at the interface between the liquid and air is utilized to measure the height of the liquid level. This contact measurement method allows the guided wave radar level sensor to obtain liquid level information more accurately, avoiding errors due to fluctuations in the liquid surface or the influence of environmental factors.
Because the probe of the guided wave radar level transmitter must contact the measured liquid, its measuring distance is relatively short. Compared to some non-contact radar level gauges, guided wave radar water level sensor require the probe to be inserted directly into the liquid, so their measuring range is usually smaller. However, this is where the guided wave radar level sensor excels, as it allows for accurate level measurements in smaller vessels or confined spaces, unaffected by external interference.
Guided wave radar level sensor has the following advantages:
1. In tanks with agitation or large fluctuations in the medium, the bottom-fixed guided wave radar level meter is more stable than ordinary radar level meter measurement.
2. More suitable for the measurement of materials in small tanks. When measuring the level of small tanks, due to the small measurement space (or more interference in the tank), the general guided wave radar water level sensor is not applicable, while the guided wave radar level sensor is not restricted.
3. The measuring principle of the ordinary radar water level sensor and guided wave radar level meter are based on the difference between the dielectric constant of the medium for measurement, due to the ordinary radar level meter of the emitted wave is scattered when the dielectric constant of the medium is too low, the signal is too weak to measure will be unstable, and guided-wave radar level meter emitted wave is propagated along the guided wave rod, the signal is relatively stable.
In general, the guided wave radar level transmitter because of its contact measurement principle, so that the measurement distance is relatively short. It is this contact measurement feature that makes the guided wave radar level transmitter excel in some specific application scenarios, providing a reliable solution for level measurement in industrial production processes.
