Verabar Compared to Orifice Plates

Through Accuracy of Measurement, Low Installed and Operating Costs, Verabar Proves Its Performance, Efficiency and Value.

Orifice Plate Test Results

Florida Gas Transmission Company conducted a test to quantify various

Savings in Weld Time

Installed Cost Savings

Verabar Lowers Installed

Costs

Verabar can save you more than 60%

in installation costs over an orifice

plate in a 10" pipe.

The graph shows the total installed

cost by pipe size of the orifice plate,

the Verabar, and the resultant Verabar savings. The most significant portion of the savings is the reduction in the linear inches of weld.

Dollar Savings $ 100,000

$ 50,000

Only 4 Inches of linear welding

Verabar pays for itself in less than a year.

The graph shows the yearly operating cost savings and equivalent horsepower

savings of the non-constricting, low

permanent pressure loss Verabar

compared to the extremely constricting,

high permanent pressure loss orifice plate. Savings are shown for gases,

liquids and steam—at typical design velocities, by pipe size.
