1 BEST COST EFFECTIVE FLOW MESUREMENT EVEN FOR LRGE SIZE LINES O-0 Series GLSS TUBE TYPE ORIFLOMETER GENERL O-0 series ORIFLO METER is a flow meter consisting of a orifice plate and a GLSS TUBE type variable area flow meter. Since the flow rate is measured with a small sized flow meter set to a bypass piping, the flow measurement even for large sized lines can be economically conducted. In addition to the local indication type, alarm contact version is also available. STNDRD SPECIFICTION Detection type : Bypass orifice type Measuring fluid : Liquids (Viscosity : up to 3mPa s) and Gases (Not suitable for slurry and steam) vailable tapping and sizes : ) D D/ taps (O- - P) 0mm to 500mm ) Corner taps (with orifice ring) (O- - C) 50mm to 500mm 3) Flange taps (O- - F) 50mm to 500mm 4) Vena contracta taps (O- - V) 00mm to 500mm Note : 550mm or more can be supplied on request. Process connection : JIS5K/K/0K, NSI/JPI CLSS 50/300 and Others.

2 O-0 Series ORIFLOMETER CPCITY OF ECH LINE SIZE FOR LIQUID PPLICTIONS S FOR GS PPLICTIONS The maximum flow rate of flowmeter can be specified in the above mentioned POSSIBLE SCLE RNGE. NOTE : bove table are based on the fact that the material of main pipe is SGP (Carbon steel pipes for ordinary pipes JIS G 345). The maximum flow rate of the main pipes other than SGP are determined by multiplying above figures by the value equal to (actual inside diameter/sgp inside diameter) to above figures. : bove table is applicable for measurement of Water (Density.0g/cm 3, Viscosity.0mPa s). When measuring liquid whose density is not.0g/cm 3, refer to the above table after calculating flow rate converted to air by the following formula. ( )/( ) Flow rate converted to water Density of float Flow rate of actual fluid Density of actual fluid Density of float 3. irflow indicates the maximum measurable flow range based on 0, atm. When operating conditions are different, refer to the above table after calculating flow rate converted to air by the following formula.

SUGGESTIONS FOR INSTLLTION 30 unit : mm. Upper/lower straight tube length. Since the pressure loss within the bypass pipe is precalculated, do a specified bypass piping in accordance with the related approval drawing. 3.
