The ultrasonic transducers alternately transmit and receive ultrasonic test signals in the direction of flow and counter to the direction of flow. The flowmeter further comprises a control/evaluation unit which determines and/or monitors the volume flow of the medium inside the container based on the difference in the travel time of the ultrasonic test signals propagating in the direction of flow and counter to the direction of flow. The ultrasonic transducers are configured such that they transmit and receive ultrasonic test signals or sound fields having a large aperture angle or a great beam expansion.

摘要： A microphone amplifier comprises an input terminal (E100) for applying an input signal (IN), an output terminal (A100a) for outputting an output signal (OUT), and an additional output terminal (A100b) for outputting an additional output signal (VBIAS). The microphone amplifier also contains an amplifying circuit (10) for generating the output signal (OUT) by amplifying the input signal (IN), wherein the amplifying circuit (10) is connected between the input terminal (E100) and the output terminal (A100a), and a voltage generator (30) for generating the additional output signal (VBIAS). A supply voltage terminal (V30) of the voltage generator (30) is connected to the output terminal (A100a) of the microphone amplifier. Since the amplifying circuit (10) makes available a supply voltage (V) for the voltage generator (30), the microphone amplifier can be operated without a separate supply voltage terminal.
