The Tube-Cube Flowmeter Brochure

The Tube-Cube®DescriptionThe Tube-Cube® is an innovative design developed and patentedby Matheson. It allows the interchange of flow tubes within asingle frame. The Tube-Cube® is standard on all Matheson FM-1050 and FM-1000 Series Flowmeters and tube assemblies. The Tube-Cube® was designed so that it could be fitted into anystandard 150mm or 65mm flowmeter unit*. This includes allmeters supplied by Matheson prior to the Tube-Cube® style designas well as those of most other manufacturers. Retro-fit Kitscomplete with end seal adapters (filler plugs and O-ring) areavailable. 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 a protective plastic rectangle that can’t roll off a bench• 1.5 X magnification of meter scale and float for easier, moreaccurate readingThe Tube-Cube® consists of two side plates of ABS resin, twomolded end pieces of high density polypropylene, and a clearmolded acrylic front shield which also serves as a magnifying lens.This lens magnifies the flowmeter tube numerals and float by afactor of 1.5 to allow more precise flow reading than is possiblewith conventional flowmeter shields. The flowmeter tube end seals are also contained in the Tube-Cube®package. These seals assure that the glass tube is preciselycentered and positively retained within the Tube-Cube® . Theseend seals are Viton as standard but are also available with Teflonin fluid contact, Buna N, and EPR (Ethylene Propylene Rubber)when specified as optional extras. To complete the package, a yellow, flexible, polished vinyl rearpanel is fitted into the Tube-Cube®. This panel not only provides areflective, easy tube reading background, but it also acts as aprotective rear cube-cover which keeps dust and dirt out of theTube-Cube® itself.
