Precise Measurement and Control Application of IP68 Ultrasonic Level Meter in Feed Production [Dayu Electronics]

　　In large-scale feed production, the precision of ingredient addition and the stability of storage level directly affect product quality and production efficiency. The IP68 ultrasonic level meter, with its core advantages of strong adaptability and precise measurement and control, has become key equipment for ingredient batching and storage tank level management in feed production. Through seamless integration with PLC cabinets via 4~20mA standard signals, it builds a fully automated measurement and control system.

　　The device employs a non-contact measurement principle, calculating level height through high-frequency ultrasonic pulse emission and reflection time difference, perfectly adapting to the complex working conditions of feed production. For dynamic level monitoring of granular and powdered raw materials in the batching process, it offers high measurement accuracy, capturing level changes in real time during material addition, providing data support for precise ingredient ratio control. In storage tank applications, the device's IP68 protection rating withstands dust, moisture, and material build-up interference inside the silo. Even under extreme environments from -20°C to 60°C, it continues stable operation, solving industry pain points of low efficiency and data lag in traditional manual measurement.

　　Core measurement and control functions are efficiently transmitted via 4~20mA analog signals, which offer strong anti-interference capability and meet stable transmission needs over distances of hundreds of meters within the workshop, accurately feeding real-time level data back to the PLC cabinet. The PLC system forms closed-loop control logic through preset level thresholds: when the ingredient silo level drops below the set value, it automatically triggers the refill switch; when the storage tank level reaches the upper limit, it promptly cuts off the inlet to prevent material overflow and waste; during the discharge phase, it dynamically adjusts the discharge valve opening based on level data to ensure production continuity. This automated control mode not only reduces errors from manual intervention but also multiplies the management efficiency of operators severalfold, significantly lowering labor costs.

　　Additionally, the device supports integration with production management systems, where level data serves as an important basis for raw material consumption statistics and inventory accounting, helping enterprises optimize procurement plans and production scheduling. Its modular design facilitates installation and commissioning, with deployment time per silo under 30 minutes, suitable for parallel operation of multiple tanks. With an annual failure rate below 1%, maintenance costs are significantly reduced. The IP68 ultrasonic level meter, with its precise and reliable measurement and control capabilities, provides solid technical support for refined management, cost reduction, and efficiency enhancement in feed production, becoming one of the core devices for the intelligent upgrade of modern feed mills.
