Question:
Which size flow meter should I choose for my installation? I would
prefer a flow meter with the same diameter as the tube(s).
Answer:
The minimum and the maximum flows determine the size. Use the size
chart (on page 18 ) to find the correct flow meter size, and avoid tending
to select a too large size.

Question:
Where do I install the flow meter in relation to valves, bends,
pumps, etc.?
Answer:
Minimum 3 times the flow meter's internal diameter (DN) up-stream,
and minimum 2 times the flow meter's internal diameter (DN) down-stream.
