3. Field Application & Customer Feedback

As Jiwei’s flagship product, the Tube‑11 Vibrating Rod Level Switch performs exceptionally in ash-level monitoring inside Longking Environmental Protection’s baghouse ash silo. Operating under heavy dust load and fluctuating temperatures, this harsh environment challenges conventional instruments. However, Tube‑11’s high-sensitivity probe and robust interference resistance enable continuous, accurate ash-level detection—greatly enhancing operational safety and automation.

Similarly, both the Cape‑11P RF Admittance Level Switch and Flap‑11P Magnetic Flap Level Gauge resolved Longking’s long-standing liquid-level measurement issues in its flue gas treatment and desulfurization loops. Engineered for corrosion resistance, these products withstand high temperature, humidity, and chemical exposure, maintaining reliable, long-term performance.
