Method and apparatus for calculating flowing medium temperature in a magnetoinductive flowmeter

摘要

A method for calculating the temperature of a medium traveling through a measuring tube, while with the aid of at least one field coil a magnetic field is generated which permeates the measuring tube. The electrical resistance of the field coil is measured and the temperature of the field coil, constituting a first temperature, is calculated based on the measured resistance of the field coil. A temperature measurement, constituting the second temperature, is taken at a location other than that of the field coil and the temperature of the flowing medium is calculated on the basis of the first and second temperatures. This provides the user of the flow measuring method an added benefit in that it gives the possibility, in simple fashion, to determine the temperature of the flowing medium. A flowmeter for measuring the medium temperature according to the method is also disclosed.
