For powder silo projects in building material, grain and new energy industries, heavy dust, material buildup on silo walls and fast material level fluctuation are common challenges for design institutes and EPC contractors. Ultrasonic sensors and low-frequency radars are vulnerable to dust attenuation, often resulting in fluctuating readings and signal loss. Improper instrument selection in drawing design stage usually leads to unstable measurement after commissioning. Site teams have to arrange frequent manual climbing inspection, raising operation cost and safety risks. The 80G radar level transmitter, with narrow beam angle and outstanding dust penetration performance, is the preferred device for continuous level measurement of bulk solids.

An EPC project with 8 fly ash steel silos (6m diameter) suffered severe dust during discharging. The original 26G radars often lost signals while unloading, making level interlock protection unavailable. After retrofitting with HCCK 80G radar level transmitters, the lens antenna and intelligent echo filtering algorithm effectively suppress interference from dust and wall deposits. Stable level signals are transmitted to the DCS system for high/low level alarm and automatic feeding interlock. Manual inspection work is greatly reduced, and this solution has been listed by the design institute as a standard specification for similar powder silos.

Lithium battery cathode powder silos demand strict explosion protection and stable data output. HCCK 80G radar level transmitters with intrinsic safety certification were specified at the engineering design phase to fit hazardous powder environments. The instrument provides 4-20mA output and supports cloud data uploading. EPC teams, design institutes and end clients can remotely check historical level curves and device status. Reliable continuous level data supports production scheduling, capacity calculation and safety interlock, preventing overflow or empty silo shutdown caused by false level readings.
