1 COST EFECTIVE FLOW MEASUREMENT FOR LIQUIDS AND GASES O-18/78 Series ORIFLO METER GENERAL O Series ORIFLO METER is a By-pass Orifice type flowmeter. Small sized variable flowmeter is installed on measuring tube part in which an orifice plate for by-pass flow is integrated. Three different process connections,i.e., "SCREW", "FLANGE" and "WAFER", are available for Selection. An isolation valve is available between measuring tube and indicar for indicar maintenance work even during process operation. This eliminates the necessity of by-pass piping for maintenance purpose and saves tal piping cost. In addition standard material of STEEL version, Stainless steel and PVC versions cover corrosive fluids are available. Alarm contacts are available as option. (O-78 Series) See quick delivery model details on page 7. FEATURES LOW COST / HIGH PERFORMANCE Thanks unique orifice by-pass system, tal instrumentation cost can be saved especially for medium and large sized piping measurement. COMPACT DESIGN Small sized indicar saves space in plants. EASY INSTALLATION "SCREW", "FLANGE" and "WAFER" are ready meet field requirements. By-pass piping for maintenance purpose can be skipped by using isolation valve. FOR ALL FLOW DIRECTIONS BOTTOM TO TOP, TOP TO BOTTOM, LEFT TO RIGHT, RIGHT TO LEFT. ORIFLO is applicable for all possible flow directions. Change of such flow direction is possible in field even after installation. ALARM CONTACT Besides local flow rate indication, alarm contact (s) are available. ORIFLO can be used as FLOWSWITCH. EASY MAINTENANCE Simple design and limited number of parts saves maintenance work. HIGH ANTI CORROSIVE CAPABILITY VERSION Stainless steel and PVC versions are available for corrosive fluid application. MAIN APPLICATIONS Hot and cool water as well as air flow measurement at Air conditioning Medium and large line measurement at General process Cooling water lines Water treatment process Pure and Ultra pure water production facilities process Testing of Fire fighting pumps Testing of blowers Others TG-F771-9E SEP. 3K TG-F771-1E NOV. 11K

2 OPERATION PRINCIPLE As shown in the figure, differential pressure is produced across the Main orifice plate by flow velocity which corresponds flow rate. A small sized flowmeter (Variable area flowmeter) is mounted on this differential pressure production unit. By this arrangement, the flow rate through the flowmeter corresponds the flow rate through the Process piping. Thus, scale range for Process piping can be engraved on the small sized flowmeter and the flow rate through the Process piping is indicated by the position of float of the flowmeter. Normally, an isolation valve is provided between the measuring tube and the indicar for the purpose of indicar maintenance with no interference of process operation. (This valve is for maintenance/ isolation purpose and not for flow control purpose.) A magnet piece is buried in the float for Alarm version which attracts reed switch for alarm contact output. The setting point of alarm is adjustable by shifting the location of reed switch.
