ABSTRACT:
Analogue measuring value signals, generated in a throughflow measuring device, are infed to a computer by means of an analogue-digital converter. The computer adds the received digital signals and produces at regular time intervals, for instance every three seconds, an output signal corresponding to the total conveyed quantity. This output signal serves to control a display device and a printer. In the display device there is displayed the total quantity of the conveyed material during a certain time span. On the other hand, the computer forms a mean or average value signal from digital signals received within a predetermined time span, for instance likewise every three seconds. This mean value signal is characteristic for the momentary throughflow of the material during this time period. This mean or average value signal likewise serves to control the display device and the printer. In the display device there is thus also displayed the momentary throughflow quantity. Due to this processing of the measuring value signals by the computer it is also possible to obtain a correct determination of the conveyed quantity of material even if the conveyed material or medium flows through the pipe conduit or line with markedly fluctuating throughflow velocity.
