Check out this massive Jacoby-Tarbox® Flanged Bulls-Eye Sight Flow Indicator we recently had out in shipping - a 10" 150# 608-FA (316 Drip Tube) unit, headed to a government application.


Breaking Down the Model Designation

  • 10" refers to the pipe connection size - a substantial diameter reflecting a high-flow-volume application

  • 150# indicates the pressure class rating (150-pound class), the flange rating standard this unit is built to

  • 608-FA is the specific model designation within Jacoby-Tarbox's flanged bulls-eye line

  • 316 Drip Tube specifies Type 316 stainless steel construction for the drip tube component, chosen for its corrosion resistance


What the Drip Tube Does

In a flanged bulls-eye sight flow indicator, the drip tube channels fluid through the viewing area in a way that allows operators to observe individual drops or a continuous stream, depending on flow conditions - giving visual confirmation not just that flow is present, but often some sense of flow rate or consistency based on how the fluid appears passing through. Constructing this component from 316 stainless steel ensures it holds up to sustained exposure to the process fluid without corroding or degrading the visual clarity of the indication.


Why ASME Compliance Matters Here

Jacoby-Tarbox's full ASME-rated line of flanged bulls-eye sight flow indicators is engineered per the design criteria of the ASME B31.1 and B31.3 Power and Chemical Piping Codes, incorporating only ASTM-listed metals in the unit's construction. This level of code compliance and material traceability is exactly what a government application typically requires - government and public infrastructure projects often carry stricter documentation and material certification requirements than typical commercial or industrial work, since these installations are subject to public accountability and often longer service life expectations.


Why Size and Pressure Class Matter for This Application

A 10-inch, 150# class unit represents a large-diameter, moderate-pressure application - the kind of sizing you'd expect on a major process or utility line rather than a smaller branch connection. Government facilities, whether municipal utilities, federal installations, or public infrastructure projects, often involve exactly this kind of large-scale piping where visual flow confirmation at this diameter matters for operational monitoring.


Applications

Large-diameter, ASME-compliant flanged bulls-eye sight flow indicators like this one are used across:

  • Government & Public Infrastructure: Municipal and federal facility piping systems requiring documented code compliance

  • Power Generation: Large-diameter process and utility piping

  • Chemical Processing: High-flow-volume lines requiring visual flow confirmation

  • Any Large-Scale Application: Where material certification and code traceability are contractual requirements
