Abstract: A flowmeter (1) comprising a sensor unit and a measuring and/or evaluation unit (8) for determining a volume flow rate, a mass flow rate and/or a flow speed of a measurement medium (5) in a tube (2), characterised in that the flowmeter (1) comprises a) the sensor unit for determining the volume flow rate, the mass flow rate and/or the flow speed of the measurement medium, which sensor unit is arranged on or in the tube (2) and b) a microphone (10, 15), which is arranged on or in the tube (2). The microphone is used for switching between an energy-saving operating mode and a normal operating mode. The microphone is likewise used for detecting changes in the state of the measurement medium.

Abstract: The invention relates to a circuit arrangement (1) for reducing power dissipation in an active current output (5) of a field device for determining and/or influencing a process variable, said process variable being represented via an adjustable current value (4-20 mA), comprising an external voltage supply, a voltage regulator (4) and a control circuit (7, 8, 9, 10) assigned to the voltage regulator (4), said control circuit (7, 8, 9, 10) being designed in such a way that the voltage regulator (4) regulates the voltage of an external load (6) connected in parallel to the current output (5) on the basis of the currently set current value (4-20 mA) in such a way that essentially only the voltage required in each case is available to the external load (6).
