The Renesas Electronics liquid flow sensor module measures the flow rate using the thermo-transfer (calorimetric) principle. It offers key advantages over resistor based flow solutions. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor comprises a “solid” thermal isolation technology with protective coating. The non-linear flow output curve allows for sensitivity from low to full-scale flow rates. It provides analog output.

It allows liquid flow up to 0 to 7 litres/min
It is built using Robust “solid” isolation technology
It is resistant to vibration and pressure shock
It provides minimal flow resistance
