Click to OpenJacoby Tarbox ® Model 100-SA (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.

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

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.
Jacoby Tarbox 100-SA-FLTR

The TFE flutter allows for easy Uni-directional indication of low flowing gases and liquids. The thin ribbon type flutter curls into the pipeline, vibrating at the slightest presence of gas or liquid movement.  The flow of the media is indicated by the intensity of the fluttering against the window of the unit.
