Abstract:
1. A measuring apparatus for producing a sequence of measured values of a measured variable, which is a function of a first auxiliary measured variable and at least a second auxiliary measured variable, comprising: a first measuring transducer for registering and for outputting a sequence of values of said first auxiliary measured variable; at least a second measuring transducer for registering and for outputting a sequence of values of said second auxiliary measured variable; an evaluating unit for calculating the sequence of measured values of the measured variable based on the sequences of values of said first auxiliary measured variable and at least said second auxiliary measured variable; and a control unit for synchronizing the registering of the sequences of said first auxiliary measured variable and at least said second auxiliary measured variable, by means of a first sequence of control signals, which is output to said first measuring transducer, and a second sequence of control signals, which is output to said second measuring transducer, wherein: at least said first sequence of control signals is variable independently of said second sequence of control signals; a first processing time is defined from a registering of a current value of said first auxiliary measured variable up to outputting of a first reference signal; a second processing time is defined from a registering of a current value of said second auxiliary measured variable up to outputting of a second reference signal; and said control unit is designed to register at least the respective points in time of output of the first reference signal and of the second reference signal and, taking into consideration the first and second processing times or a difference between the first and the second processing times, and to vary the control signal for at least one measuring transducer, in order to minimize deviations between the point in time of registering the respective current value of said first auxiliary measured variable and at least the point in time of registering the respective current value of said second auxiliary measured variable.
