nominal diameter for reasons relating to measurement accuracy.
An inlet section of ≥ 5 x DN is required for Q-75.
The inlet section must be designed as a straight pipe section with the same
nominal diameter as the meter.
The length of the outlet section is at least 1 x DN of the same nominal diameter.
The flow through the meter must be free of vibrations/pulsations in order to
avoid measuring errors.
The gas may not contain suspended particles > 50 μm.
