Magnetically inductive flow rate measuring system for determining volume- and/or mass flow rate of measuring medium in e.g. automation engineering, has two resistance thermometers integrated into two electrodes, respectively

摘要

The system has a heatable resistance thermometer (2) i.e. thin film resistance thermometer, attached at a base surface (5) of a blind hole (4) in an electrode (1) e.g. acute electrode and mushroom head electrode, and integrated into the electrode. A casing is arranged between the thermometer and a wall (6) of the blind hole, and is made of a thermally insulating material. The electrode has an outer surface (7) contacting a measuring medium in a measuring tube in an operating condition. Another resistance thermometer is integrated into another electrode. An independent claim is also included for a method for determining flow rate of a measuring medium.
