The Automatic Dosing System is a fully integrated, PLC-controlled solution designed for precise, continuous chemical dosing in water treatment, industrial process, and environmental protection applications. It automates the preparation, mixing, and metering of chemicals such as flocculants, coagulants, pH adjusters, scale inhibitors, and disinfectants.

+86 15936525232The system operates through a closed-loop, automated workflow:
1. Chemical Preparation: The raw chemical is automatically fed into the mixing tank and diluted to the required concentration under continuous stirring.
2. Level Monitoring: A level sensor continuously monitors the liquid level, triggering automatic feeding or low-level alarms as needed.
3. Precise Dosing: A metering pump delivers the prepared chemical solution to the process pipeline at a controlled, adjustable flow rate.
4. Automatic Control: The PLC controller adjusts the dosing rate based on real-time signals from flow meters, pH/ORP sensors, or turbidity meters, ensuring optimal chemical dosage.
Fully Automatic Operation: Eliminates manual dosing, reducing labor costs and human error. The system runs continuously with minimal supervision.
High Precision & Stability: Equipped with a high-precision metering pump and closed-loop control, ensuring accurate and consistent chemical dosing.
Modular & Compact Design: Skid-mounted, space-saving design that integrates tanks, pumps, mixers, valves, and the control cabinet for easy installation and commissioning.
Corrosion-Resistant Construction: Made of food-grade PE or stainless steel tanks, with anti-corrosion pumps and wetted parts, suitable for a wide range of corrosive chemicals.
User-Friendly Control: Features a touchscreen HMI with adjustable parameters, automatic alarms for low level, pump failure, and abnormal dosing, ensuring operational safety.
Easy Maintenance: All components are standardized and easily accessible for routine inspection and replacement, minimizing downtime.
