A magneto-inductive flow measuring device including a coil arrangement and a circuit for controlling a supply voltage of the coil arrangement. The circuit is designed to provide the supply voltage of the coil arrangement with a voltage curve sequenced as follows: A) the voltage rises from a starting voltage I up to an overvoltage II; B) in given cases, the voltage is held at the overvoltage II; C) the voltage falls from the overvoltage II down to a holding voltage V. The circuit controls the fall of the voltage from the overvoltage down to the holding voltage by tuning the voltage to at least two or more predetermined, intermediate, desired values III, IV. |
