SUP-RD702 — Guided Wave Radar Level Meter

The SUP-RD702 is a guided wave radar level meter dedicated to corrosive duty. All wetted parts are PTFE, so acids, alkalis and other aggressive chemicals can be measured directly without remote seals or exotic alloys — with ±5 mm accuracy and temperature ratings to 200 °C.

Wetted parts
Full PTFE
Media
Acid, alkali, corrosive
Principle
TDR guided wave
Output
4-20 mA / HART (opt.)
  • ✓Full PTFE wetted parts direct measurement in HCl, H₂SO₄, NaOH and more — no seals needed.
  • ✓Non-contact-free reliability guided pulse ignores vapour and turbulence above the liquid.
  • ✓Compact and light installs through a small threaded or flanged nozzle.
  • ✓Maintenance-free no moving parts, no fill fluid, no drift.

Frequently Asked Questions

Which acids can it handle?

PTFE is inert to nearly all acids including concentrated HCl and H₂SO₄; share your concentration and temperature for a confirmed selection.

Why guided wave instead of non-contact radar here?

In small corrosive tanks, guided wave avoids antenna fouling and gives a stable, foam-proof reading.

Can the probe be replaced?

Yes — probes are replaceable, so a damaged rope or rod can be swapped without replacing the transmitter.
