Abstract
The flow of a fluid of unknown composition is measured by leading the fluid over a first temperature sensor, a heater and a second temperature sensor. The temperature difference DTP between the temperature sensors is measured, as well as the temperature T of at least one of them. In addition, calibration data is used to store the temperature Tref of a known reference fluid. The offset T−Tref at a given temperature difference DTP is a direct measure of the composition of the fluid and allows to retrieve any parameter depending on the same.
