Line Installation
All fl anged Venturi fl ow elements require a gasket between the process line connection and the
mating fl ange. Select gaskets that match the pressure rating of the Venturi fl anges and resist corrosive
attack of the process fl uid.
Before completing the bolting process, be sure that the gaskets are properly centered so that
protrusion into the pipe opening is minimized. Misalignment may cause added fl ow turbulence.
However, performance eff ects are typically minimal depending upon the application. Bolt the
element in line with suitable hardware using recommended bolt torques for the type and class
rating of the fl anges.
Torque all models per ANSI fl ange ratings.
Tighten the fl ange bolts in a progressive "star" pattern to avoid localized stress on the gaskets.
