All popular sizes and materials of construction are available, with flanged, threaded and special connections, as well as rotator, flapper, drip-tube or plain indicator styles. Also included are threaded, oblong and conventional sight windows.

Jacoby Tarbox Sight flow indicators provide an effective way to view the condition of liquids or solids flow through pipelines at most any flow, pressure, or temperature, a major advantage over electronic devices where it is difficult to distinguish if there is a flow problem or malfunction in the device. 

Jacoby Tarbox Sight Flow Indicators assure a direct and positive indication of flow rate, flow direction, and condition of the medium being transported plus enable a means of inspecting pipelines for dirt, scale, and foreign matter.

Economical, easy to install, and an inexpensive investment for installations in viewing stations at many points throughout a processing system, Jacoby Tarbox  distributes sight flow indicators worldwide to meet routine as well as the most punishing applications.  The complete line offers a wide range of body materials, gasket materials, glass types, window designs, rubber lined, corrosion-resistant TFE-lined indicators.  All major styles are offered in a variety of sizes with threaded, flanged, or other end connections; operating pressures from 20 PSIG to 3000 PSIG; and are fully ANSI Rated or Nominal ANSI Rated.  Special Jacoby Tarbox indicators can be designed to accommodate specific application requirements for virtually every phase of liquid movement.

Valuable for minimizing or eliminating downtime, plant engineers can view actual line conditions and the quality of oil used to lubricate plant equipment.  With steam processes, Jacoby Tarbox  indicators enable personnel to detect, at a glance, the presence of condensate and to promptly take steps to eliminate it.  By clearly showing drops in flow rates and discoloration of material when filters become clogged, corrective action can be taken immediately.  In applications involving the processing of solids, straight-through sight flow indicators are recommended.
