3.1.4 Pipe System Requirements
The straight run requirements presented below represent the minimum requirements
for accurate flow measurement. For optimum performance, provide as much additional
straight run as possible.
IMPORTANT NOTE
For proper operation, install the flow meter in a straight run of pipe free of bends, tees, valves,
transitions and obstructions for a distance of at least 3 diameters upstream and 2 diameters
downstream.
i
Recommended Installation
Place pipe at least 3 pipe
diameters downstream and
2 pipe diameters upstream
from bends and obstru-
tions.
Avoid downward flow
which can lead to partially
filled pipes.
The electrodes should
be located in the
horizontal axis (3 o’clock
and 9 o’clock) in order to
prevent sediment from
settling on them.
Avoid these installations
