An insertion flow meter is installed in a straight pipe run to maintain unobstructed access and accurate water flow rate readings. The layout requires a minimum straight pipe distance of ten pipe diameters upstream and five pipe diameters downstream of the meter sensor. Arrows indicate the required direction of water flow through the piping assembly.
