Description

This high quality brass two-in-one sensor package is designed to monitor both liquid flow and liquid temperature within a pipe. These are ideally suited for monitoring water consumption in irrigation control systems or other forms of liquid automation. Each side of the sensor has a 1/2″ BSPP G-1/2″ thread. The sensor has a three pin connector for the hall-effect flow sensor and a two pin connector for the temperature sensor.

Inside the housing, a small pinwheel with an attached magnet is spun by passing water; as the magnet makes each revolution, a hall effect sensor inside the housing outputs a pulse on the yellow wire. The sensor is best suited to flow rates between 1 and 25 liters per minute – flow rates below one liter per minute tend not to register accurately. The temperature sensor is an NTC 50K Thermistor.

For flow rates less than 6 liters per minute, we recommend looking at the YF-S401 with a higher resolution / lower flow rate.
