In cases such as these, decide whether to use a guided-wave radar or a contactless radar level gauge

The medium in the reaction tank is liquid, and foam is generated during the reaction process. Is it possible to measure the foam level? If so, is it better to use guided wave technology or a non-contact method?
I would like to ask why contactless ones don’t work? Is it because the energy of the contactless electromagnetic waves is lost after passing through the foam?
The amount of electromagnetic waves received will certainly decrease, but as long as the waves can be sent back and received, that’s sufficient. However, if the power is low, the waves may not be able to penetrate the foam and return; it’s better to use a higher power level
If there is foam, non-contact measurement is inaccurate
Forget contactless options for now; check how thick the foam layer is. If it’s two to three centimeters thick, a guided wave radar level gauge can be used for direct installation. If the layer is thicker, it’s better to use a guided wave radar together with a guided wave tube for installation
