Low Flow Glass Tube Flowmeters

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 conguration 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 conguration 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

• Magnier 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

Metering Tubes

• Heavy-wall, precision
bore

• Borosilicate glass

• Removeable without
disconnnecting instrument

Features and Benets

Threaded Jack Screw

• Tubes sealed on compression gasket

Self Aligning Blocks

• Allows for easier tube alignment and
replacement

Clear Polycarbonate

Faceshield

• Built-in magnier for
easier oat and scale
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 specic
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

• NRSTM (Non-Rising Stem)

• Integral Flow Controllers
