High Pressure Flanged Bulls-Eye Models 300 & 600 ASME Class


Jacoby-Tarbox’s full ASME rated line of flanged bullseye sight flow indicators have been engineered per the design criteria of the ASME B31.1 & 31.3 Power & Chemical Piping Codes, incorporating only ASTM listed metals in the unit’s construction.  This standard setting group of features include full ASME code compliance with regards to yield criteria, materials, and pressure/temperature ratings.


• Connections per ASME B16.5, B16.24, and B16.1
• Standard fasteners per ASTM A354 and ASTM A194 complying with most piping specifications.
•Tempered borosilicate glass
• Units and machined and assembled in an ISO-9001 fully automated facility.
• Wetted components meet NACE MR-01-75 / ISO15156-1 requirements.
• Stainless steel engraved identification faceplate.

FULL BORE VISIBILITY: Pipeline view is maximized, in most cases with a diameter that is equal to the nominal pipe size, allowing 100% unobstructed process observation of gases, solids, solutions, and slurries.

PRESSURE DROP: Non-Rotor models offer minimized pressure drops with their non-restricting, smooth, full-bore construction.

APPLICATIONS: Jacoby-Tarbox ASME flanged units are ideal for piping, process, and mechanical engineers that wish to maintain full ASME compliance within their pipelines.  Refining, chemical, power, and pharmaceutical industries are just a few areas of Jacoby-Tarbox’s successful code applications.  O.E.M.’s specify this series when maximum reliability in harsh operating service is desired.
