FM TESTING UPDATES

The official FM report is final.  The new venturi design and Digital Gauge w/ 4-20ma transmitter is now FULLY FM Approved from 2″-12″ line sizes.

GVI Patented Venuri

The United States patent office has reviewed and accepted the newly designed GVI venturi patent application.  This mean GVI now offers a Patented venturi design that reduces friction loss, has less cavitation, no bounce, and accuracy of 0.5%.

3rd Party testing on the GVI flow meter

We know from the flow curves and data that the new Patent Pending venturi design from GVI is outstanding.  But we wanted to see the results in action.  We shipped a box off our shelves to a certified lab for installation and testing.  GVI was NOT running this test, nor even onsite.  These are the results.  Click here!
