Water Flow Sensor (Sea) DN80 Flowmeter 20-500L/min 3.5-12V
The water flow sensor with an aluminum body is a reliable flow meter capable of accurately measuring liquid flow rates ranging from 1 liter per minute to 120 liters per minute. Internally equipped with a Hall effect sensor, it detects the movement of blades induced by the liquid flow, generating a square pulse signal whose frequency corresponds to the flow rate. Its rugged mechanical design is suitable for 3-inch piping, ensuring durability and ease of installation. Additionally, it features environmentally friendly encapsulation, making it user-friendly and ideal for various applications.
In operation, the sensor utilizes magnets installed at the ends of blades within the flow meter. As these magnets rotate, they generate a variable magnetic field that is detected by a Hall effect sensor. The electronic circuit then converts this detection into pulses, which are transmitted via a cable. These square pulses, representing flow rate data, are transmitted through the yellow wire and must be connected to a pulse counter for further processing and monitoring.
