FS400A Water Flow Sensor - 1" Thread, 1-60 L/min, Digital Pulse Output
The FS400A is a Hall-effect water flow sensor with a 1″ threaded interface, designed for inline installation in water systems. It outputs digital pulses proportional to flow rate, compatible with 3.5-12V DC logic for integration with microcontrollers (Arduino, Raspberry Pi), PLCs, or flow controllers.
Features
- Hall-effect sensor with magnetic rotor for reliable digital pulse output.
- Broad flow measurement range from 1 to 60 liters per minute (L/min).
- Rugged 1-inch (24.5mm) threaded plastic body for easy inline installation.
- Wide operating voltage range of 3.5 to 12V DC for flexible system integration.
- Designed for water pressure up to 1.75 MPa and temperatures from 0 to 80°C.

The FS400A water flow sensor operates on a Hall-effect principle. Water flow drives a magnetic rotor assembly; as the rotor speed varies with flow rate, an integrated Hall sensor generates corresponding digital pulse signals. This pulse-frequency output provides a direct, linear relationship to volumetric flow, enabling precise measurement and control.
Engineered for durability in water applications, the sensor features a stainless steel bearing and ball assembly for smooth, low-friction rotation and enhanced sensitivity. The Hall element is epoxy-encapsulated and isolated from the water path, ensuring long-term reliability and protection against oxidation. The construction complies with ROHS standards, making it suitable for various residential and light industrial water monitoring systems.
