Patent ID: 7012418

Claim:
A measuring system comprising a measuring device ( 1 ) with a digital interface ( 5 ) and an evaluation unit ( 2 ), wherein the measuring device ( 1 ) is a mass flow meter whereby the interface ( 5 ) has a clock input ( 3 ), to which a pulse generator ( 4 ) is connected, a signal input ( 10 ), to which a measured signal is applied, an arithmetic; unit ( 6 ) that generates an output signal derived from the clock signal and the measured signal, and a signal output ( 12 ), where the output signal is output and transmitted to the evaluation unit ( 2 ), wherein the interface ( 5 ) has a further signal output ( 13 ) where a reference signal derived from the clock signal is output, whereby the reference signal is used by the evaluation unit ( 2 ) to correct the output signal.
