  • NG # 04099-HW-SUPMEA-054

  • MF # SUP-RD702

The SUP‑RD702 Guided Wave Radar Level Meter is an industrial radar level measurement instrument designed for continuous level detection in liquids and bulk solids, particularly suitable for corrosive media. The device uses guided wave radar technology, where high‑frequency microwave pulses travel along a probe and reflect from the surface of the material being measured. With robust construction and versatile installation options, it provides reliable level measurement for tanks, vessels, and process systems across chemical, industrial, and corrosive environments.
