Xiamen JingchuanSpecialized small flow high-precision electromagnetic flowmeter for dosing systemCore technological advantages
Small flow high-precision measurementUsing self-developed high-frequency square wave excitation technology, combined with high-sensitivity Hall sensors, specially optimized for the small flow range of 0.05-10L/h in the dosing system, the measurement error is strictly controlled within ± 0.2%, and the repeatability is ≤± 0.1%. Even when facing precipitation prone agents such as PAC (polyaluminum chloride) and PAM (polyacrylamide), or corrosive media such as acid and alkali, special electrode designs (optional tantalum and platinum materials) and dynamic signal compensation algorithms can accurately capture subtle fluctuations in flow rate. In the flocculation and dosing process of sewage treatment, the injection amount of chemicals can be monitored in real time to avoid water quality exceeding the standard due to insufficient dosing or waste and secondary pollution caused by excessive dosing, providing accurate data support for cost accounting.
Deep adaptation to dosing scenariosIn response to the common problems of narrow pipelines and easy adhesion of media in the dosing system, the flow meter adopts a DN3-DN15 small-diameter design, which can seamlessly connect to the outlet pipeline of the dosing pump without the need to modify the original system. The inner wall of the flow channel is lined with PTFE (polytetrafluoroethylene) and polished with a mirror finish to reduce drug residue and adsorption, especially suitable for high viscosity lime milk. The built-in bubble recognition and compensation algorithm can effectively eliminate the measurement deviation caused by dissolved gases during the dosing process, ensuring stable operation under various dosing conditions, and covering over 95% of the dosing system requirements with adaptability.
Anti interference and stable operationThe body adopts a fully metal shielded shell, combined with an independent grounding design, which can resist electromagnetic interference generated by equipment such as motors and frequency converters in the dosing room, ensuring stable measurement data. The contact medium components are made of corrosion-resistant materials such as 316L stainless steel and PTFE, which can withstand long-term corrosion from acid, alkali, salt solutions, and organic agents. They are suitable for various media such as disinfectants, reducing agents, and heavy metal capture agents commonly used in dosing systems. The protection level reaches IP65, suitable for humid and dusty environments in the dosing room, with a working temperature range covering -10 ℃ -60 ℃, and can operate continuously in complex outdoor or workshop conditions.
Intelligent linkage and convenient operation and maintenanceSupports 4-20mA analog signals and RS485 digital transmission (Modbus RTU protocol), seamlessly integrates with the PLC control cabinet and metering pump of the dosing system, and achieves closed-loop flow control. When the deviation between the actual flow rate and the set value exceeds ± 0.5%, the dosing pump frequency is automatically adjusted to accurately control the amount of medication injected. For example, in the pH adjustment system of municipal sewage treatment plants, the sodium hydroxide flow rate is adjusted in conjunction with online pH meter data to stabilize the effluent pH value within the standard range of 6-9, and the dosing accuracy is improved by 20% -25%. Built in self diagnostic function, can monitor electrode contamination, excitation faults and other issues in real time and issue alarm prompts. The electrode adopts a detachable structure, supports online cleaning and replacement, and the calibration cycle is extended to 6 months, greatly reducing operation and maintenance costs.
