DN40 G1-1/2 Water Sensor Switch — Hall Effect Turbine Meter (Range 5–150 L/min) Key benefits Accurate, responsive flow measurement across a wide range (5–150 L/min) for consistent process control and reliable monitoring. Hall Effect switch output provides a clean, repeatable pulse signal for counting, flow rate display, or integration with controllers and monitoring equipment. Compact DN40 form factor with G1-1/2 BSPT male thread makes the unit easy to fit into existing inline piping, reducing installation time and mechanical changes. Reduces guesswork and manual checks by delivering real-time flow feedback, helping prevent overuse, detect anomalies, and optimize pump and valve operation. Main features Function: Turbine flow meter with Hall Effect switch output for pulse or switch-based flow detection and metering. Flow range: 5–150 L/min (suitable for low to medium flow applications). Connection/size: DN40 body with G1-1/2 inch BSPT male thread for standard pipe connections. Installation and wiring: Simple inline installation and straightforward wiring; clear interface size and detailed specifications are provided to support correct mounting and electrical connections. Versatility: Designed for use where reliable liquid flow sensing and switching are required. How this solves common problems Improves control: Accurate flow data enables automatic control of pumps and valves to maintain target flow rates and reduce energy use. Enables early detection: Continuous measurement helps identify leaks, blockages, or abnormal flow conditions before they escalate. Simplifies upgrades: Standard G1-1/2 BSPT connection and Hall Effect output make replacement or retrofitting fast and compatible with common systems. Typical applications Petrochemical industry: Inline flow monitoring and switching for process lines, feed control, and safety interlocks. Residential area control and waterworks: Metering distribution lines, managing pump stations, and detecting abnormal consumption. Farmland and garden irrigation: Controlling irrigation circuits, monitoring water usage, and automating valve operation for consistent coverage. Practical notes Ensure the mating BSPT female thread and pipe bore match the DN40 interface for a leak-free installation. Hall Effect output can be tied into counters, flow displays, PLCs, or alarm systems; follow the detailed wiring specification provided with the unit. Supplier documentation includes interface dimensions and electrical details to simplify selection and installation. This DN40 G1-1/2 Water Sensor Switch Hall Effect Turbine Meter delivers a dependable, easy-to-install solution for accurate flow measurement and control across a variety of industrial, municipal, and agricultural applications.
