ABSTRACT A device for metering liquid flow in a dispensing line for a gas-pressured beverage comprising a flowmeter with electrical contacts pulsing as an indication of fluid flow in said line, an electrical impulse generator, an impulse counter having multiple outputs corresponding to different counts in the counter, and an electronic calculator with a preset calibrated value stored in its memory and electrically con- nected to said outputs for activation of respective ones of its functions, said contacts being serially located in that one of the connections assigned to an addition function of said calculator whereby with each pulse of said contacts the total value displayed by said calculator is increased by the value stored in said memory, and the maximum signal input response rate of said calculator exceeds the pulsing rate of said con- tacts indicative of a flow of fluid with a gas content below a predetermined level and is less than the pulsing rate of said contacts indicative of a flow of fluid whose gas content is above said level.
