Over two years of engineering
and design have resulted in a new industry standard for
visual flow indicator technology.
Uncompromising levels
of quality, safety and technological excellence are standard
features in the complete line of L.J. Star Incorporated
Standard Threaded Model visual flow indicators.
Description
All standard
threaded models in the L.J. Star Incorporated line of
visual flow indicators carry full ANSI rating and are
available in several application-specific configurations.
ANSI designed for 150 psi or 300 psi, threaded units are
available in sizes from 1¦2" to 2".
Styles
Threaded
units are available in four styles designed to accommodate
various mounting positions, fluid characteristics, flow
rates and directions:
• Plain Style
May be installed in
any position to observe fluid flow in any direction.
These style indicators are usually employed to detect
either the presence or absence of solutions, or to observe
fluids for turbulence, color or clarity.
• Drip Tube Style
This style is well suited
for vertical lines with downward flow direction. These
units are particularly recommended for applications
characterized by low or intermittent flow rates, such
as distillation processes.
• Flapper Style
Recommended for monitoring
either horizontal or vertical lines with upward flow.
The flapper position indicates current flow rate. Flapper
style indicators are the appropriate choice for use
with clear and semi-opaque solutions.
• Rotator Style
This style indicator
may be installed in any position to indicate flow in
any direction. The visibility of rotor motion makes
this style particularly well-suited for monitoring clear,
translucent or dark solutions.
