Xiamen Jingchuan small flow electromagnetic flowmeterCore technological advantages
DN6 small caliber precise adaptation dosing pipelineUsing customized DN6 small-diameter measuring pipes, it can directly connect to common DN6 dosing pipelines in sewage treatment dosing systems (such as metering pump outlet pipes) without the need for variable diameter adapters, reducing pipeline resistance and drug retention. The inner wall of the measuring tube is lined with corrosion-resistant PTFE material, which has undergone mirror polishing treatment. This not only reduces the adhesion and residue of chemicals, but also avoids the blockage of the flow channel by PAC, lime milk and other easily precipitated chemicals. It is suitable for the operation requirements of small flow rate and small pipe diameter in the dosing system.
High frequency excitation technology ensures measurement accuracyEquipped with high-frequency square wave excitation technology (excitation frequency up to 100Hz), combined with high-sensitivity tantalum electrodes, optimized for the small flow range of 0.1-8L/h in the dosing system, with measurement error controlled within ± 0.5% and repeatability ≤ ± 0.2%. Even in the face of high viscosity PAM solutions or highly corrosive hydrochloric acid and sodium hydroxide agents, dynamic signal compensation algorithms can be used to eliminate medium characteristic interference, accurately capture subtle fluctuations in flow rate, and avoid water quality exceeding standards due to insufficient dosing or chemical waste caused by excessive dosing.
Resistant to corrosion and pollution, adaptable to sewage dosing environmentThe core components that come into contact with the chemicals are made of 316L stainless steel and PTFE composite material, which can withstand common acid and alkali corrosion and chemical oxidation in the sewage treatment dosing process. The service life is extended by 50% compared to ordinary flow meters. Built in bubble recognition and elimination function, which can eliminate the influence of dissolved gases on metering during the dosing process; The flow system is equipped with an automatic backwash interface, which can regularly clean the residual chemicals in the pipe by backwashing with clean water, reducing the frequency of manual maintenance and adapting to the humid and dusty dosing room environment of the sewage treatment plant.
Intelligent linkage optimization of dosing processSupports 4-20mA analog signals and RS485 digital transmission (Modbus RTU protocol), seamlessly integrating with PLC control cabinets and online water quality monitoring devices in sewage treatment dosing systems to achieve closed-loop flow control. When abnormal effluent quality (such as pH value and turbidity) is detected online, the flow rate of the reagent can be automatically adjusted to ensure stable treatment effect. For example, in the sludge dewatering and dosing process, the PAM flow rate is adjusted in conjunction with the sludge concentration data to control the sludge moisture content within the target range, reducing the consumption of chemicals by 15% -20%.

Xiamen Jingchuan sewage treatment dosing flowmeterTypical application scenarios
Flocculation and dosing processIn the front-end coagulation stage of sewage treatment, precise measurement of PAC (polyaluminum chloride) flow rate is carried out to control water turbidity, ensure subsequent sedimentation effect, reduce the amount of sludge in the sedimentation tank, and lower the subsequent treatment load.
Acid alkali neutralization and dosingTo meet the demand for adjusting the pH value of industrial wastewater, stable measurement of the flow rate of acid-base agents such as hydrochloric acid and sodium hydroxide is carried out. Through closed-loop control, the pH value of the wastewater is stabilized within the treatment range of 6-9, avoiding equipment corrosion or increased difficulty in subsequent treatment caused by excessive acidity and alkalinity.
Disinfection and dosing monitoringAt the end disinfection stage of sewage treatment, monitor the dosing flow of disinfectants such as sodium hypochlorite and chlorine dioxide to ensure that the residual chlorine in the effluent meets the standard, while avoiding secondary pollution and cost waste caused by excessive disinfectant.
