Jacoby Tarbox ® Sight Flow Indicators

Standard Jacoby Tarbox ® sight flow indicators can be specified to accommodate very specific application requirements.  Special Jacoby Tarbox ® indictors can be designed and manufactured to meet unique installation, processing or flow criteria.  Specifiers may choose from a wide range of indicator body materials, gasket materials, glass types and window designs, plus special corrosion-resistant lined indicators.

Click to OpenJacoby Tarbox ® Model 100-S (Flapper Style)
This unit employs a 316SS hinged wheel weighted flapper to indicate flow media.  The velocity of the flow is indicated by the position of the flapper. Uni-directional, these units are optimal for horizontal or vertically upward flows.

These units are bi-directional and may be placed in any orientation.  Used primarily in processes where spot indication is desired to detect presence of media, or to inspect color, clarity, turbidity, or other critical characteristics.
   
Model 200S Model 300S
Click to OpenJacoby Tarbox ® Model 200-S (Drip Style)
Low, intermittent flows are easily detected with this Uni-directional style in the horizontal or vertically downwards direction.  The drip tube forces the process to collect on the lower lip of the 316SS tube, allowing it to visibly drip downward
Click to OpenJacoby Tarbox ® Model 300-S (Rotory Style)
The TFE rotor allows for easy bi-directional, multiorientational flow direction.  The speed  of the rotor indicates the relative velocity of the media.  Ideal for opaque liquids or heavy gases for an easily contrasting detection at far viewing distances.  Extra durable stainless steel rotors are available as an option.
