Straight inlet
ULTRAFLOW® 54 requires neither straight inlet nor outlet in order to fulfil the Measuring Instruments Directive (MID)
2014/32/EU and EN 1434:2015. Only in case of heavy flow disturbances before the meter will a straight inlet section be
necessary. We recommend following the guidelines in CEN CR 13582.
Optimal position can be obtained by taking the below-mentioned installation methods into consideration:
