Abstract
An ultrasonic flow measuring device which provides a flow measuring device characterized by a low electrical current consumption and low power uptake. At least one component of high power uptake with a control/evaluation unit is provided, with the control/evaluation unit being designed such that the component of high power uptake is operated intermittently in a measuring phase and in an idle phase, with the component being activated in the measuring phase, while, in the idle phase, the component exhibits a reduced power uptake or is completely turned off.
