1 BEST COST PERFORMANCE R-1-E GLASS TUBE FLOWMETER GENERAL R-1-E is a glass tube type variable area flowmeter. The flow rate is indicated by the position of float and the graduation engraved on the glass tube. Although it has a very simple construction, it is widely used for measurement of flow rate of liquids and gases in various applications thanks to its high reliability and easy handling capability. A large d tapered tube is adopted compared to standard type glass tube flowmeters and wide scale range is possible. In addition to standard material of steel and stainless steel, is also available for corrosive applications. STANDARD SPECIFICTION Available : to Measuring fluid : All kinds of liquids and gases (Not suitable for steam measurement. AM series Metal Tube Flowmeters are recommended) Available material Fittings : Carbon steel, SUS0,, HT-* : Heat-resistant glass (Acryl tapered tube is available on request.) If the fluid temperature exceeds C, the heat-resistant glass tapered tube is only available. Float : For liquids SUS0,, HT-* others For gases Aluminium, SUS0, others * High temperature use : NBR, EPDM, FPM Process connection Standard : JISK flange Option : ANSI, DIN, other flanges Rc, NPT (upto mm) Flow direction : Bottom to Top Press. range Max. fluid press.

TOKYO KEISO CO., LTD. Cautions on the use of glass tube variable area flowmeters CAUTION Avoid the use of glass tube variable area flowmeters for the following services. 1. Liquid services subject to impulse pressure in the process.. Secondary accidents might occur due to the breakage of glass in such services : Toxic fluids such as poisons, stimulant and narcotics Flammable fluids Explosive fluids. Gas handling process where breakage of glass might result in gas leakage or scattering of glass fragments.. The installation places of the flowmeters where breakage of glass might be caused by the accidents from the surrounding piping or equipment. 5. On-off operation where breakage of glass might be caused by the collision of the float inside meter due to the abrupt change of flow. 6. Services where the heat shock by abrupt change of temperature is expected. TG-F7-11E
