The Brooks® Sho-RateTM Series glass tube variable area ow meter has been the industry standard glass tube variable area meter for decades. This glass tube meter
is ideal for a variety of gas and liquid applications. These meters are particularly
suited for purge applications. The base conguration uses a borosilicate glass tube
installed in an aluminum frame with 316SS end blocks, adaptors, and valve. Additional material options, valve options, and ow controllers are available to provide
the appropriate conguration for a wide variety of applications.
Features
• Standard direct read scales on tube for all uids and uid conditions
(user selected)
• Standard millimeter scales with ow curves for all uids and uid conditions
(user selected)
• Scale length (approximate) 65mm, 150mm
• Magnier built into front shield
• Flowmeter options:
Multiple tting adapters for all world areas
No valve, cartridge valve and precision control valve
Inlet & outlet valves
Integral ow controller, upstream & downstream
Multiple connection ttings to t all applications

reading
Rugged, Single Piece Frame Construction
Interchangeable Tubes and
Floats with Direct Reading (DR)
Scales on the Tube
• Allows users to change ranges
as the application dictates
• DR Scale on Tube is determined
by the user; based on specic
application needs
• Eliminates reading errors
introduced by detached scales;
resulting in a more accurate
indication of ow
Integral Float Stops
• Prevent loss of oat during tube
removal
Optional Valves for Inlet or Outlet
• Cartridge III Valves
