Flow Sensor

WiFi Flow & Temperature Sensor

Product Information


WiFi enabled device
SensorLinx Compatible

The WFS Sensor is a combined flow and temperature sensor (two-in-one). The sensor is fully compatible with wet, aggressive liquids. The sensor is based on the principle of vortex shedding behind a bluff body. The sensor is based on MEMS sensing technology in combination with the corrosion-resistant Silicoat® coating technology on the sensor chip. The sensor is a lightweight and robust compact flow meter than can be installed in tight spaces vertically or horizontally. The sensor can be used for many applications including flow metering for individual tenant billing.
