Dinghua Radar Instrument Training School: Radar level gauges use guided waves in practical operating conditions. Radar level gauges enable non-contact measurement, and generally speaking, non-contact measurement has many advantages. However, in some special operating conditions, non-contact measurement can present certain problems. If there are obstacles in the area through which the microwave beam travels, such as ladders, heating equipment, supports, limit switches, etc., these elements can affect the propagation of microwaves, thereby impacting the measurement performed by the radar level gauge. The measurement of radar level gauges is carried out using microwaves; when these microwaves encounter an obstacle during their propagation, they are reflected. Under normal conditions, in an environment where the measurement setup is relatively simple, it is possible to determine the position of the material quite easily by using an oscilloscope. However, in some relatively complex measurement environments, the obstacles that microwaves encounter during propagation are not just materials; as a result, multiple echoes are generated, which ultimately makes it impossible to determine the location of the materials with accuracy. In light of the above situation, we need to use some special methods to resolve this issue at this time. Using an installation waveguide or bypass channel can effectively solve this problem; through such a waveguide or bypass channel, we can effectively avoid the influence of obstacles that interfere with measurements. Of course, this only applies in certain specific operating conditions, as only media with good fluidity can enable the guide wave tube or bypass tube to be at the same level as the main container being measured; viscous media are not suitable for this purpose. It is also worth noting that the inner walls of the waveguide or bypass channel must be smooth as well, in order to ensure that the flow of the medium is not disrupted. To avoid affecting the measurement. Finally, a critical requirement for the takeover is that the antenna must extend at least 10 mm into the tank.
