PRESO COIN LOCATION INSTRUCTIONS

Straight pipe requirements: Accuracy is affected by the piping configurations due to
the disturbances of the flow profile. A fully developed symmetrical flow profile is
achieved with the minimum upstream and downstream recommended lengths.

NOTES:
1 -

For upstream and downstream lengths equal to one half the values shown
add 1 percent to the accuracy value.

2 -

Any flow conditioner shall be installed in the straight length between the
primary element and the upstream distance, or the fitting closest to the
element. The straight lengths between fitting and conditioner shall be at
least 10D and the length between conditioner and Coin Meter shall be at
least 15D.

3 -

For other fittings, configurations, contact PRESO.
