Abstract: An electronic unit comprises a microcontroller with a control input, a control output, and a signal input; and an interface circuit with a connection terminal, a control output, a control input, and a signal output. Both the microcontroller and the interface circuit each have a first operating mode and a second operating mode. The microcontroller is designed to cause the interface circuit to operate in its first operating mode. The interface circuit is designed to convert an input signal into a derivation signal representing a derivation of the input signal over time and to generate a control signal from the derivation signal. The microcontroller is designed to cause the interface circuit to operate in its second operating mode and to receive and convert a digital input signal and to output an output signal to the microcontroller.

Abstract: The present disclosure recites a method for time controlled carrying out of a filling process including steps of beginning a first flow measurement before or during the start of a filling of a first container, starting the filling of the first container at a first point in time, and ending the filling of the first container at a second point in time, wherein the second point in time is predetermined by a set, first time interval. The starting and ending steps are repeated for filling a second container. The method also includes ending the first flow measurement and ascertaining a total flow of the preceding fillings, comparing an actual value ascertained from the total flow a predetermined, desired value, and-adapting the first time interval based on the comparing step. An apparatus according to the present disclosure includes a control setup for time controlled fill amount control and a flowmeter.
