Metering pumps provide customers with intelligent solutions for precise chemical dosing. Digital metering pumps innovatively employ stepper motor vector drive, advanced MCU (microcontroller unit), and customized software programs to achieve precise metering and dosing over a wide range. The digital metering pump features a simple mechanical structure, convenient installation and maintenance, and integrates multiple intelligent designs. Manual/automatic and remote/local modes are available. It monitors and controls flow rate, level, pressure, time, and safety alarms, using an integrated microprocessor for automated calculation and feedback. It also supports two-way communication via the Modbus RTU protocol, and a user-friendly human-machine interface (HMI/LCD) system makes operation more convenient.
