The MUL3 guided wave radar transmitter sends microwave pulses down a rod or cable probe and measures the reflection from the product surface. Because the signal is guided, it delivers ±3 mm accuracy regardless of temperature, pressure, density, vapor, dust or foam — and it can measure straight through foam layers.
Top mounting minimizes leak risk, and the probe principle works in small tanks, complex geometries and tanks with internal obstacles, as well as in existing bypass chambers. An echo-curve display makes commissioning with the four local keys straightforward.
Key Features
- Direct, precise level and interface measurement with no compensation for changing process conditions
- No moving parts and no recalibration — minimal maintenance
- Handles vapor, dust, turbulence and foam; measures through foam
- Probe materials and connections for strong acids and alkalis (316L + PTFE antenna parts)
- Options to retrofit existing bypass chambers as a complete solution
