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.
Savings in Weld Time Installed Cost Savings
Verabar Has the Lowest
Operating Costs
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.
Verabar vs. Orifice Operating Cost Savings
Through Accuracy of Measurement, Low Installed and Operating Costs,
Verabar Proves Its Performance, Efficiency and Value.
Verabar Maintains Its
Accuracy
Orifice plates show long term
deterioration of accuracy.
The initial accuracy of the orifice
plate is ±1%. However, long term
accuracy deteriorates unless the plate
is periodically inspected. Senior, dual
chamber fittings are available to check
the plate without requiring system
shutdown, but such fittings are very
expensive.

Orifice Plate Test Results
Florida Gas Transmission Company
conducted a test to quantify various
conditions which can result in inaccu-
rate measurement. A partial list of the
