6.4.1 Selecting and Location

be considered in order to provide maximum safety and accuracy.
Safety: In order to provide prevent chemicals from being added when there is no flow to the pool, the flow
meter should be installed in the main return line after the filter.
Accuracy: in order to ensure accuracy, the flow meter should be installed in a straight run of pipe following
the minimum requirements listed in Table 10.
