This section should be at least 5 pipe diameters longwith respect to the size of the Flow Meter.½” [DN15] 5 x nominal pipe size = 2.5” [64 mm]¾” [DN20] 5 x nominal pipe size = 3.75” [95 mm]1” [DN25] 5 x nominal pipe size = 5” [127 mm]1¼” [DN32] 5 x nominal pipe size = 6.25” [159 mm]1½” [DN40] 5 x nominal pipe size = 7.5” [191 mm]2” [DN50] 5 x nominal pipe size = 10” [254 mm]Outlet LengthNo requirements for outlet length.Elbows can be installed directly after the valve.5 x Nominal Pipe Size (NPS)PIPINGThe Flow Meter is suitable for volumetric flow measurement of chilled or hot water in closed loop systems. If the Flow Meter will be installed tomeasure fl ow through a heat exchange device, it is recommended to be installed on the return side of the heat exchange device.
