Guided wave radar level meter used for agitator tank

April 02, 2020

Since the agitator tank can meet different process and production requirements, it is also inseparable from the guided wave radar level meter. This is because the agitator tank will increase the fluctuation range of the medium when stirring the material. In this case, the measured value of guided wave radar level meter is more stable than that of ordinary radar level sensor.

 

 

As far as I know, most people think that the performance of contact guided radar level meter is not as good as that of non-contact radar level meter. In my opinion, the truth is that this is not the case and both types of level sensors have advantages and disadvantages. In general, most of the medium in the agitator tank are flammable, explosive or highly corrosive. Therefore, it mainly uses the mechanical seal method to isolate the contact between the medium and the air. At this time, the probe of the guided wave radar liquidometer can calibrate the measured data by detecting the echo signal at the bottom to avoid exposing the medium to the air. In addition, the principle of measurement of the guided wave radar data are based on dielectric constant, and the launch of common radar level gauge is divergent wave, when low power saving constant, the signal will be unstable, at the same time, non-contact measurement radar blind area will increase with the increasing range, but most of these agitation tank range are more than 30 meters.

Because the guided wave radar level meter is a contact measurement, this means that it needs to consider the adhesive and corrosivity of the medium. Even though its range can reach 60 meters in theory, the excessively long guided wave radar level meter will increase the installation time and the later maintenance cost.
