Equipped with an automatic control system and high - precision metering pumps, the automatic dosing device can accurately inject various chemicals according to water quality changes, enabling efficient water treatment and cost optimization. It is a reliable choice for industrial circulating water, sewage treatment, and other scenarios.
The automatic dosing device takes the metering pump as the main dosing equipment, and assembler the dissolving tank, agitator, liquid level gauge, safety valve, check valve, pressure gauge, filter, buffer, pipeline, valve, base, ladder, automatic monitoring system, power control system, etc. on a common platform according to the process flow requirements to form a module. That is, the so-called skid-mounted modular unit (referred to as "skid-mounted body"). The working process of putting a certain amount of chemicals into the stirring solution tank as needed for stirring and dissolution, and then sending them to the dosing point through a metering pump after dissolution is completed.
Chemical Storage: Pour flocculants, corrosion inhibitors, disinfectants, and other chemicals into the storage tank. The tank is equipped with a liquid - level sensor to monitor the chemical inventory in real - time.
Signal Collection: Real - time water quality data is collected through online water quality monitoring instruments (such as pH meters, conductivity meters, turbidity meters) and transmitted to the PLC control system.
Intelligent Calculation: The PLC control system calculates the required chemical dosage based on preset programs and real - time water quality data.
Precise Dosing: The metering pump injects the chemicals into the target water pipeline or treatment tank at the set flow rate according to the control instructions.
Feedback Adjustment: The system continuously monitors water quality changes and dynamically adjusts the dosage to ensure that the treatment effect meets the standard.

How to set the chemical dosage?
The fixed dosage can be preset through the PLC control system, or automatically adjusted according to water quality monitoring data. Parameters can also be modified in real - time through remote terminals.
How to troubleshoot equipment failures?
The system has a built - in fault diagnosis function, and alarm codes can be viewed through the control cabinet display. Common problems such as low - level alarms and metering pump blockages can be repaired according to the instruction manual.
Can multiple chemicals be dosed simultaneously?
Multi - pump and multi - tank configurations are supported, allowing the simultaneous dosing of 2 - 4 different chemicals, with independent control of the dosage and time for each chemical.
The automatic dosing device has become a key equipment in the water treatment field for improving efficiency and reducing costs, thanks to its precise dosing, intelligent control, and wide applicability. Whether in municipal sewage treatment or industrial circulating water maintenance, efficient and stable operation can be achieved through customized configurations. In the future, with the application of Internet of Things and big data technologies, automatic dosing devices will further optimize control strategies, providing intelligent and energy - saving chemical dosing solutions for more industries.
