The TUBE CUBE
| Description |
 |
The Tube
Cube is an innovative design developed and patented by Matheson
Instruments. It allows the interchange of flow tubes within a
single frame. With the Tube Cube you can quickly and easily
change flow ranges without having to disconnect the flowmeter
from your system to change the entire frame. The TUBE CUBE is
standard equipment with all Matheson Instruments FM-1050 and
FM-1000 Series Flowmeters and tube assemblies.
|
|
The
TUBE-CUBE was designed from its inception so that it could be
fitted into any standard 150mm or 65mm flowmeter unit*. This
includes all meters supplied by Matheson prior to the TUBE-CUBE
style design as well as those of most other manufacturers.
Retro-fit Kits complete with end seal adapters (filler plugs and
O-ring) are available.
*Cannot
be used on Fisher and Porter Models, 10A 1450, 10A 1460, 10A
1300, 10A 3135 and Porter Models F65A, and F15A Forged Body
Meters.

| The
TUBE-CUBE offers you: |
- Easier
and faster installation.
- Automatic
centering and alignment.
- Elimination
of chipped tube ends.
- Insurance
of safer and proper installation. Whenever the tube is
installed the seals are correctly located.
- Protection
from tube breakage because the glass tube is always encased
in protective plastic rectangle that can't roll off a bench.
- 1.5
magnification of meter scale and float for easier, more
accurate reading.
|
The
TUBE-CUBE consists of two side plates of ABS resin, two molded
end pieces of high density polypropylene, and a clear molded
acrylic front shield which also serves as a magnifying lens.
This lens magnifies the flowmeter tube numerals and float by a
factor of 1.5 to allow more precise flow reading than is
possible with conventional flowmeter shields.
|
The
flowmeter tube end seals are also contained in the TUBE-CUBE
package. These seals assure that the glass tube is precisely
centered and positively retained within the TUBE-CUBE. These end
seals are Viton® as standard but are also available with Teflon®
in fluid contact, Buna N, and EPR (Ethylene Propylene Rubber)
when specified as optional extras.
|
To
complete the package, a yellow, flexible, polished vinyl rear
panel is fitted into the TUBE-CUBE. This panel not only provides
a reflective, easy tube reading background, but it also acts as
a protective rear cube-cover which keeps dust and dirt out of
the TUBE-CUBE itself.
