Abstract

An ultrasonic flow measuring device, which determines volume and/or mass flow of a medium in a pipeline, or in a measuring tube. The flow measuring device includes a plurality of ultrasonic sensors, which emit and/or receive ultrasonic measurement signals along defined sound paths. The control/evaluation electronics of the flow measuring device is divided into an on-site electronics, in which at least one switch is provided, via which the ultrasonic sensors, arranged in different sound paths, can be driven and/or queried, and at least one remote, control/evaluation unit, wherein the control/evaluation unit so switches the at least one switch, that the driven and/or queried, ultrasonic sensor, or the driven and/or queried pair of ultrasonic sensors, is activated and provides measured values.
