Abstract (en)
[origin: EP1203886A2] The measuring method uses a heating element (17), e.g. a positive temperature coefficient resistance, inserted in the flow medium for periodic heating of the latter, with comparison of the temperature characteristic of the heating element with predetermined values, for determining at least one material characteristic of the flow medium. An Independent claim for a pump unit with a device for measuring at least one characteristic of the flow medium is also included.
