The flow sensor is a precise measuring instrument used to monitor liquid flows in various applications. It activates a relay as soon as a certain flow rate is reached, with the switching point adjustable via an integrated potentiometer. This allows for flexible adaptation to different requirements. The sensor is equipped with two red LEDs that indicate the operating status, as well as a green LED that provides additional information. Additionally, it features a 7-segment display that offers a clear and easily readable presentation of the relevant data. The flow sensor is designed for use in a temperature range of -10 to 50 degrees Celsius, making it versatile. With a compact design and robust construction, it is ideal for industrial applications as well as for use in building technology. The item is sold as a single unit and provides a reliable solution for monitoring flows.
