摘要： The invention relates to a thermal measurement device for determining and/or monitoring the mass flow of a fluid medium (3) through a pipeline (2) or through a measurement tube, comprising at least two temperature sensors (11, 12) and a regulation/analytical unit (10), both temperature sensors (11, 12) being resistance elements of which one is of a design which may be heated, both temperature sensors (11, 12) are arranged In a region of a housing (5) facing the medium (3) and are in thermal contact with the medium (3) flowing through the pipeline (2) or measuring tube. The regulation/analytical unit is provided with two differing precision resistances (R1, R2), the first precision resistance (R1) having a first defined value (Y1) and the second precision resistance (R2) having a second defined value (Y2), wherein the regulation /analytical unit (10) assigns a measured resistance (Rx1; Rx2) determined on a resistance element (11, 12) a measurement value (Y1; Y2) lying on a straight line (g) running through two calibration points ((R1, Y1), (R2, Y2)) provided by two precision resistances (R1,R2) and the regulation /analytical unit (10) determines the mass flow through the pipeline (2) or the measuring tube from the measured values (Y1,Y2) provided by the temperature sensors (11, 12).

摘要： The invention relates to a device for determining and/or monitoring the mass flow rate of a fluid medium through a conduit (2) or through a measuring tube. Said device has at least two temperature sensors (11, 12) and a control/evolution unit (10), both temperature sensors (11, 12) being located in a region of the housing (5) facing the medium (3) and being in thermal contact with the medium (3) flowing through the conduit (2) or through the measuring tube. A first temperature sensor (11) and a second temperature sensor (12) are configured as to be heatable. The first temperature sensor (11) and the second temperature sensor (12) can be alternately actuated to be a passive, non-heated temperature sensor providing data on the actual temperature of the medium (3) during a first measuring interval, and as an active, heated temperature sensor providing data on the mass flow rate of the medium (3) through the conduit (2) or through the measuring tube (2) during a second measuring interval. The control/evaluation unit (10) outputs a message and/or carries out a correction of the recorded mass flow rate if the measured values of the two temperature sensors (11, 12) acquired during the first measuring interval and during the second measuring interval differ from each other.
