The above diagram shows a typical installation set-up for the MPC Visual Flow Indicator, to help ensure proper flow is reaching the working application. Of course, a VFI can be placed at any point on your line where you want to monitor flow. A VFI unit can be installed in virtually any orientation without compromising the unit's performace.

The photo below shows panel-mounted VFI units monitoring the flow of five separate lines. (Note: panel mounting is optional.) This photo shows two different size lines in use, but any combination of 1/4", 3/8", 1/2", 3/4" or 1" NPT lines can be monitored using a similar set-up. The dome size of all our VFI units is the same for easy set-up and upgrading.
