Sight Flow Indicators

Flanged Connection / Window Type
Construction: Bronze, Carbon Steel or Stainless Steel

 

Flapper

Pressure Rating: 150 PSI

EFI 910-F Sight Flow Indicators are recommended for both horizontal and vertical pipe lines with upward flow.  These units are best suited to transparent or slightly opaque solutions.  Position of flapper indicates flow.  May be supplied without flapper where no internal indicator is required.

Models EFI 910-F or 608-F

Page 41 - 910-F

Drip Tube

Pressure Rating: 150 PSI

EFI 608-F Sight Flow Indicators are best adapted to vertical downward flow.  The models are particularly useful in distillation and similar apparatus where flow is apt to be intermittent.  They are designed without any obstruction to handle the intermittent flow as well as full flow.

Rotating PTFE Wheel

Pressure Rating: 150 PSI

EFI 935-F Sight Flow Indicators operate successfully in any position but are particularly adapted to pipe lines carrying dark opaque solutions where the motion of the wheel is easily detected.  This model is equally adapted to transparent solutions and is frequently installed where observation must be made from a distance.
