So sind bei Einsatz einer Abtastregelung mit digitalem Regelalgorithmus Umschaltfrequenzen aufeinanderfolgender Heiz- und Messphasen von mindestens Hz realisierbar. Advantageous embodiments of the invention are subject of the subclaims. In the context of the embodiment of the static thermal measurement error is first determined numerical calculations for different installation and ambient conditions using a specific meddiumstemperatur sensor construction using.

Inside a pl ea t, t he flow ve locity rem ai ns practically [ Dabei wird in der beschriebenen Art und Weise mittels der digitalen Regeleinrichtung Here, in the described manner by means of the digital controller 2 2 bzw.

Meidumstemperatur, this is provided for pressure and temperature compensated sensing the mass flow of a medium device provides one hand, for many applications to inaccurate measurement results and on the other hand, to non-dynamic. In the method of the temperature sensor and at least one reference temperature sensor are determined before the actual measurement signal curves are being evaluated as a signal curves temperature-time characteristics.

Since the two sensor elements SE1 and SE2 are made the same, and in particular identical temperature-dependent resistance elements R1 and R2, preferably based on platinum, the thermal masses, and in particular its thermal time constants corresponding to the same or identical.

Depending on whether and if so to which of the at least three sensor elements there is mediummstemperatur change in the thermal resistance, do not have to be optionally run through all three time intervals. If the currently measured temperature correction terms from those which are determined at the time of manufacturing of the respective sensor element and stored, for example in the electronics unit, differ, and the deviation exceeds a predetermined limit, can be closed to a change in the electrical resistance of the deviation.
