Key features and benefits Low voltage operation: uses DC 5V to 24V, compatible with lowpower controllers and microcontrollers Accurate flow sensing: 1/2 inch Hall Effect flowmeter for reliable water flow measurement Wide flow range: 130 L/min at up to 1.75 MPa, suitable for many household and small equipment applications Easy pipe integration: G1/2 inch male thread for straightforward installation on standard water pipes Versatile use: mainly used for water switch control of electric appliances such as water heaters, humidifiers, and drinking fountains Broad applicability: suitable for a wide range of instruments to measure the flow of fluid in pipes Specifications at a glance Working voltage: DC 5V–24V Flow range: 1–30 L/min Pressure rating: up to 1.75 MPa Type: 1/2' Hall Effect Flowmeter Thread: G1/2' male thread Applications and use scenarios Automatic water heater control: install inline to monitor water flow and drive a switch that turns the heater on or off based on demand. Humidity control in devices: use in humidifiers to regulate water supply and maintain stable humidity levels. Drinking fountain flow regulation: integrate to ensure consistent water delivery and prevent flow fluctuations. Additional notes The flowmeter is designed for measuring the flow of fluid in pipes and can be used across a broad range of instruments requiring fluid flow data. Suitable for standard piping connections due to the G1/2' male thread.
