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.
