The meter is designed to withstand outdoor conditions.
F series meters must be mounted at the vertical (twelve o'clock)
position on horizontal pipe only.
U & D series meters must be mounted on vertical pipe only.
The pipe must be completely full of water at all times.
See the minimum straight length of pipe requirement chart above.
The meter can accurately measure flow from one direction only.
U-series meters measure upward flows only.
D-series meters measure downward flows only.

The meter’s accuracy is affected by disturbances such as pumps,
elbows, tees, valves, etc., in the flow stream. Install the meter in a
straight run of pipe as far as possible from any disturbances. The
distance required for accuracy is 10 times the nominal pipe diameter
before the meter and 4 times the nominal pipe diameter after the meter.
