SUP-RD701 — Guided Wave Radar Level Meter

The SUP-RD701 guided wave radar level meter sends microwave pulses down a rope or rod probe, making it immune to foam, vapour and turbulence. It measures liquids, interfaces and bulk solids up to 30 m with millimetre accuracy, and withstands process temperatures to 250 °C.

Principle
TDR guided wave
Probe
Rope / rod / coaxial
Media
Liquids & bulk solids
Output
4-20 mA / HART (opt.)
  • ✓Foam and vapour immunity the guided pulse travels the probe — surface foam cannot deflect it.
  • ✓Interface measurement detects oil/water or solvent/water interfaces in one instrument.
  • ✓Solids capability ropes handle powders and granulates in silos up to 30 m.
  • ✓High temperature and pressure rated to 250 °C and 4 MPa for demanding processes.

Frequently Asked Questions

Rope or rod probe?

Rods up to 4 m for clean liquids; flexible ropes for longer ranges and silos; coaxial probes for low-ε liquids and clean duty.

Can it measure two layers at once?

Yes — the RD701 reports the upper product level and the oil/water interface simultaneously.

What about buildup on the probe?

Light buildup is compensated by the TDR algorithm; heavy sticky products should be discussed with our engineers.
