Frequently Asked Questions
Which models are suitable for solid materials?
WSR550 can be configured for solid level measurement. SUP-RD905 is intended for powders and solid particles, while SUP-RD903 and SUP-RD904 are designed for longer-range solid-material applications involving dust, crystallization or condensation.
What is a radar level meter?
A radar level meter uses microwave signals to determine the distance to a liquid or material surface. The transmitter converts the measured distance into level, volume or another configured process value.
Are all radar level meters non-contact?
No. Conventional radar level transmitters send microwave signals through the space above the medium and do not contact the product. Guided wave radar transmits microwave pulses along a rod or cable probe that is in contact with the medium.
What is the difference between 80 GHz, 60 GHz and 26 GHz radar?
Higher-frequency radar generally provides a narrower beam and can be useful in compact vessels, tanks containing internal structures and some solid-material applications. Supmea's WSR550 operates at 76–81 GHz, WSR201 operates at 57–64 GHz, and the SUP-RD900 series uses 26 GHz technology. The appropriate frequency should be selected according to the medium, range, vessel structure and installation conditions.
Can radar level meters measure both liquids and solids?
Yes, but the model and antenna must match the application. Supmea provides models for liquids, corrosive media, powders, solid particles and open-water monitoring. Guided wave radar models are also available for selected liquids and bulk solids.
Which model is suitable for corrosive liquids?
SUP-RD901 uses a PTFE sensor for compatible corrosive liquids. SUP-RD702 is a guided wave radar model with a PTFE probe configuration for compatible acids, alkalis and other corrosive media. Chemical compatibility must be confirmed before selection.
