Abstract: Disclosed is a thermal flowmeter for measuring mass flow of a medium in a measuring tube, comprising: a measuring tube having a tube wall and a tube axis; a sensor with four probes, extending from a sensor base into the measuring tube, wherein the probes are adapted to heat medium, to determine its temperature or to influence a flow of the medium; and an electronic circuit, adapted to operate the probes and to create and to provide flow measured values. Each probe has a probe base and a probe active portion, wherein the probe active portion is adapted to heat the medium, to determine the temperature of the medium, and/or to influence a flow of the medium. The probe bases define a rhombus on a surface of the sensor base, wherein the rhombus is defined by geometric centers of cross sections of the probe bases.

Abstract: The method of the present disclosure is used to monitor a condition of a measurement sensor comprising an oscillator, which has a measuring tube for conveying the medium, and a condition parameter dependent upon a further physical parameter. The method comprises: determining tuples containing a value of the physical parameter and an associated value of the condition parameter; assigning the tuples to a value range of the physical parameter; and forming a reference value of the condition parameter for this value range of the physical parameter using the value of the condition parameter when no valid reference value of the condition parameter for this value range is present; or comparing the value of the condition parameter of the tuple with the reference value when a reference value of the condition parameter for this value range is present; and generating a finding on the basis of the result of the comparison.
