Title: Measuring DC voltage with unwanted superimposed AC component - by integrating up between identical AC voltage phase conditions
Inventor: SCHWARZ CHRISTIAN DIPL ING
IPC: G01R15/00
Filed: 1980-10-29
Abstract: The method for determining the valve of a direct voltage with a superimposed disturbing alternating voltage enables the influence of the unwanted a.c. component on the measurement result to be minimised. It involves integrating up the voltage to be measured starting from a defined phase condition of the a.c. voltage. The integration is continued for a defined time and then terminates when the same a.c. voltage phase condition is reached within a further time window. The duration of the time window can be varied up to a maximum of 5 per cent of the defined time and is pref. between 0.5 and 2 per cent of the defined time. The phase condition is defined as the null crossing of the a.c. voltage in one or other direction.

Patent DE-3105382-A1 (DE)
Title: Switching arrangement for processing the measurement signals of magnetically inductive flow meters
Inventor: BONFIG WALTER KARL PROF DR ING
IPC: G01F1/60
Filed: 1981-02-14
Abstract: This circuit arrangement applies a test voltage, which is locked to the frequency of the useful voltage, interval by interval to a band-pass filter (8). The input and output phase of the band-pass filter (8) is matched by means of a phase comparison stage (9) via a control stage (10) and a memory (11). After the phase-matching has been completed, the memory (11) is disconnected from the control stage (10) and the resonant frequency of the band-pass filter (8) remains stable when the measurement voltage is then applied to it. This prevents a phase rotation. <IMAGE>
