Victaulic Style 734/734S Orifice/ Indicator flow metering system (orifice type) provides an accurate and
economical way to obtain flow measurements
For proper installation, 2 1/2" to 4" (65 - 100 mm) sizes have a minimum straight pipe requirement of 5 diameters
upstream and two downstream; for 5" (125 mm) and up, 10 diameters upstream and four downstream. Standard
rating for Style 734 is 250 PSI (1725 kPa) at 230°F (+110°C) water.

§ For Styles 733, 734 & 734S, C (Flow Co-efficient) is Q (Flow in GPM) for P (Pressure Drop) of 1* H20.
Formula to determine Q (GPM), given C:
Q(GPM) = C x
Values for flow of water at +60°F (+16°C) for 1 inch of water (0.25 kPa) pressure drop in Gallons per Minute (Liters per Minute).
