weighted mean error ( WME) #02089
g range of a metering module including only one meter is known beforehand and when this range is smaller than the maximum specified measuring range of the meter, it is recommended to determine the WME and adjust the meter over the actual operating range only and update the markings accordingly.

weighted combination of errors of a meter or a metering module. When the specified measuri The WME is used to adjust the error curve as close as possible to zero The WME is calculated as follows: where: - n greater than or equal to 6 being the number of measurements i performed at different flowrates Q ; i
