A textile heat flow meter sensor flexible and permeable to water vapor was developed.

A proper calibration corresponding to the intended purpose of use is required for the textile flow meter sensor.

The flow meter sensitivity depends on temperature. For applications with a large variation in temperature, the compensation is required.

The textile flow meter sensitivity has a significant and complex variation with the variation in moisture content.

The textile flow meter sensor can measure the heat flow and the heat losses by evaporation.
