Device for determining and/or monitoring mass flow rate of e.g. liquid, has evaluation unit determining information about measurement of measuring units and correction value for determination of values

摘要

The device has an evaluation unit (A) determining a value for a mass flow rate of a medium based on a difference between temperatures measured by temperature sensors (T1-T3). The unit maintains a heating element (H) at a preset temperature to determine another value for the mass flow rate, where the element is arranged along a flow direction of the medium. The unit corrects measurement of measuring units (M1, M2) based on the values. The evaluation unit determines information about the measurement of the measuring units and a correction value for the determination of the values. An independent claim is also included for a device for determining and/or monitoring deposition of substance.
