In fact, guided wave radar level meters also have a very wide range of advantages. In certain special conditions, the performance of a guided wave radar level meter far exceeds that of a non-contact radar level meter. Therefore, it is essential to explore the advantages of guided wave radar level meters, which may help some users quickly select the most suitable level meter model.
One of the most important components of the guided wave radar level meter is the detection component, this component is equivalent to the antenna of the non-contact radar level meter, which is the channel for microwave transmission. This transmission method, with its concentrated signal and low signal attenuation rate, greatly improves the stability and accuracy of the measurement, especially for low dielectric liquid medium measurement, the advantages of the guided wave radar level meter are more obvious.
The microwave emitted by the non-contact radar level meter is dispersive, and when the dielectric constant of the measured medium is too low, the reflected signal attenuation is too large, and it is easy to measure the liquid level. This is not the case with guided wave radar level meters, where the emitted and reflected microwaves propagate through the detection assembly, resulting in low attenuation, strongly reflected signals, and stable measurements.
The above point is the main advantage of the guided wave radar level meter, in addition, the guided wave radar level meter generally has a bottom detection function, and the measurement results can be corrected according to the bottom echo signal, making the signal more accurate and stable.
Guided wave radar level meters are not only advantageous for level measurement with low dielectric constants, but also for working conditions where foam is generated. In foam-generating conditions, the echo signal tends to be attenuated, resulting in inaccurate or unmeasurable measurements. The special transmission channel of the guided wave radar level meter greatly reduces the occurrence of this situation and ensures a stable measurement.
Everything has its inevitability. For the relatively non-dominant measurement method of guided wave radar level meter, as a user in need, you should also know its advantages and drawbacks in order to choose the most suitable product.
