Split case pump - flow meter installation question:
As indicated in NFPA 20, the distance from the flowmeter to either isolation valve should be as recommended by the meter manufacturer.
Based on your own experience, do fittings (elbows or bends) need to be included in this distance calculation?
For example - should the distance recommendation length of 10-diameters be calculated from the last fitting or is the fitting ignored and only calculated from the isolation valve? Thank you.
