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.
