摘要： The disclosure relates to a thermal mass flow meter for determining a material flow through a vessel. The mass flow meter has at least two measuring elements immersed into a vessel with a flowing medium, with one of the measuring elements being heated. It is proposed that the heated measuring element is arranged in front of the unheated measuring element in the flow direction of the medium for at least part of the time, and for part of the time the unheated measuring element is arranged in front of the heated measuring element.

摘要： A method and an apparatus for diagnosis of a flowmeter are disclosed. The method includes thermally coupling a first sensor unit of the flowmeter to a fluid and thermally coupling a second sensor unit of the flowmeter to the fluid. The method also includes actively heating or cooling the first sensor unit by applying power to the first sensor unit such that its temperature is different from the temperature of the fluid, and simultaneously actively heating or cooling the second sensor unit by applying power to the second sensor unit such that its temperature is different from the temperature of the fluid, and typically from the temperature of the first sensor. The method can include determining a temperature TM0 of the fluid, and determining at least two independent quantities related to the heat transfer of the sensor units, each of the at least two independent heat transfer related quantities being determined from at least one element selected from the group including TM0, TM1, TM2, PM1, and PM2, and determining a diagnosis result by setting into relation the at least two independent heat transfer related quantities.

摘要： The disclosure relates to a thermal mass flow meter for determining a material flow through a vessel. In this case, a heating element is mounted on a holder which is immersed into a vessel with a flowing medium. It is suggested that the holder is subdivided into two zones of differing thermal conductivity, the holder substantially having a high thermal conductivity adjoined by a short zone of low thermal conductivity in which the heating element is arranged.
