The devices equipped with the integration function (totaliser) can calculate the integral, that is to say “totalize” the analogue signal, using any period of time.
A typical field of application is flow measurement. In this case, an analogue sensor measures the flow quantity per time unit in a pipe and displays the momentary flow value (e.g. litres per minute). The integration function (totaliser) calculates, from this constantly fluctuating quantity, a “total”, that is to say it defines the absolute quantity that has flowed through the pipe (e.g. in litres).
