B+B Sensors FLW-122 Gas Flow Sensor

This thermal sensor is designed to measure gas flow rates. Two platinum resistance elements are mounted on a single chip, one for heating and the other for measuring a reference temperature. The sensor uses a measure of the supply voltage to calculate the heat loss of the heating element due to the gaseous flow rate over the sensor. The design of the sensor enables high reproducibility and long-term stability, making the device suitable for gaseous measuring media, building automation, automotive engineering, medical engineering, device monitoring, cooling devices, food industry, etc.

• Measures gaseous flow rates up to 100m/s
• Small sensor size gives short heating periods and fast response times
• No mechanical parts
• Easy to analyse and calibrate
