R-100 Series GLASS TUBE FLOWMETER SIMPLE, BUT RELIABLE BEST COST PERFORMANCE GENERAL FEATURES MODEL CODE

Transcription

1 SIMPE, BUT REIABE BEST COST PERFORMANCE R-0 Series GASS TUBE FOWMETER GENERA R-0 is a glass tube type variable area flowmeter. The flow rate is indicated by the position of 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. R-700 series having alarm contact are also available. (Refer to separate TECHNICA GUIDANCE for details.) FEATURES DIRECT OBSERVATION OF FUID In addition to flow rate measurement, direct observation of fluid can be done through glass tube. This is effective for quality control of process line. COST EFFECTIVENESS This is the most cost effective device for local flow measurement. Very widely used for various applications. EASY INSTAATION No adjustment is required after installation. No straight run for upstream and downstream is needed. This results easy piping design. EASY MAINTENANCE Very simple construction offers almost "NO MAINTENANCE OAD". PURE MECHANICA CONSTRUCTION Flow rate is measured by pure mechanical action and no utility supply such as electric, air...required.

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 3. 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 inside meter due to the abrupt change of flow. 6.
