SIGHT FLOW INDICATORS

 Drip tube type sight flow
 indicators are recommended for
 downward vertical flow.

 This model in particular is suitable
 for distillation apparatus and such
 similar applications with
 intermittent flow.

 They are designed to allow flow
 without any obstructions to the
 flow so that there is no pressure
 drop across indicator.
 
 These indicators can be used for
 horizontal flow as well.

 Sight flow indicators with rotating
 wheel are recommended for dark
 liquids where flow is detected
 easily by motion of the rotor.
 
 Rotating wheel type indicators
 can be used with transparent
 gases and liquids as well.
 
 These indicators are suitable for
 any flow direction.

 Flapper type sight flow
 indicators are best suited for
 horizontal flow, these indicators
 can be used for vertically
 upward flow as well.
  These design sight flow
 indicators are recommended
 for transparent and slightly
 opaque solutions.
  The position of flapper in
 horizontal flow gives an
 indication of the flow rate as
 well.
