Its scale range is shown in the column Scale range 2 as marked gray. Full-scale flow rates for the PVC lining pipe are calculated based on the inner diameter of ESLON ESLOCOAT LX tee fittings (Sekisui Chemical Co., Ltd). The maximum rating is 1 MPa. If you use other fittings, additional calibration is needed. Please check D and L in the figure at the end of this document and the kind of pipe, and then contact us *2 Scale ranges of 20, 25, 2 mm size for 2 MPa class are shown in the brackets in above table. * The inside diameter of main pipe of 20 to 2mm in 1MPa class is based on the three-way socket (JIS B 201).(The three-way socket shall be attached upon request.) *4 The inside diameter of main pipe of 20 to 2mm in 2 MPa class is based on three-way socket (Sch 40). The three-way socket is supplied by customer. *5 The inside diameter of main pipe more than 40mm in 1 MPa class is based on SGP (JIS G452) Carbon steel pipe for piping, and the inside diameter in 2 MPa class is based on the carbon steel pipe for STPG (JIS G 454 Sch 40) for pressure piping.

Cap nut (S1.5) Pitot tube Bolts (4), Washer Fitting Socket Screwing 2) To install the flowmeters, drill a hole of 5mm diameter into the pipe having more than or equal to 40mm diameter. Use the three-way socket for the pipe having 20 to 2 mm diameter. Select and drill the hole at right place so that the final fixed posture of tapered tube should be vertical. ) Weld the socket to the drilled hole. The centerline of the socket must be perpendicular to the one of the pipe. 4) Screw the CFW1000 into the welded socket to complete the installation TOKYO KEISO CO., LTD. TG-F98-6E
