  • Replacing the servo gauge with Qinwei's 26 GHz explosion-proof radar ended our maintenance headaches. The reading has been stable through filling and heating cycles, and the high-high alarm now gives us overfill protection we actually trust.

  • The 80 GHz radar solved in one step the three problems that plagued our ultrasonic meters — condensation, foam and speed-of-sound drift. Our wet-well pump control is finally dependable, with no false pump commands since the changeover.

  • Density no longer matters — the radar reads the surface directly, so we get one true number whether the tank holds oil or syrup. It survives our hot caustic CIP cycle and the crevice-free sanitary connection is exactly what our auditors wanted to see.

  • Even in the heaviest dust cloud during filling, the 26 GHz radar kept tracking the true surface, and the air purge kept the antenna clean. We no longer climb the silos to recover a stuck plumb-bob — silo inventory is finally a number we can act on.
    Mr. Rafiqul Islam

  • Filling used to mean unreliable readings and a risky manual dip. With echo tracking we get a trustworthy level right through the turbulence, splash and foam — overfill protection is now valid exactly when we need it, during loading.
