A lineup from 2m to 50m! High-precision water level measurement in millimeter units is possible! Suitable for monitoring water levels in rivers, channels, dams, wells, and groundwater.
The "HM-300/700/920" is a pressure-type water level sensor that uses a diaphragm at the sensor tip to measure liquid pressure, converting changes in that liquid pressure into electrical signals for output. It is suitable for long-term water level monitoring in applications such as manhole pumps, river level observation, and sea tide observation. 【Features】 ■ Pressure-type water level sensor ■ Available in a range from 2m to 50m (HM-920 is up to 10m) ■ Capable of high-precision water level measurement in millimeter units ■ Output signal of 4-20mADC with built-in amplifier circuit ■ Built-in lightning protection element (excluding HM-920) *For more details, please refer to the PDF document or feel free to contact us.
