Abstract
A microcontroller and a method are provided for determining a flow velocity with an electronic processing unit of an ultrasonic travel time flow meter with arbitrary waveform signals. The electronic processing unit has receiver and transmitter terminals, a signal processing unit and a signal generating unit that is configured to generate an oscillating electric output signal with a time dependent amplitude, wherein the time-dependent amplitude varies according to stored signal parameters.
