Water Pressure Requirement: This LCD-M digital liquid metering controller requires water pressure (0.5-8 kg) to function. It will not work in environments without pressure.
Pipe Diameter & Calibration: Different pipe diameters require setting different K-values on the display to ensure accurate measurement. The K-value can be adjusted for calibration.
Display Language: The display content is in English. The panel is available in both Chinese and English, but the default panel language is English.
Purchase Reminder: Before purchasing, confirm the required function and pipe diameter to ensure compatibility with your system.
