● Cable entry

● Standard full scale range [PVC lined pipe]

● Standard full scale range [2MPa version = 20~32mm]

Note

1) The inside diameter of pipe size 20 to 32mm in 1MPa is based on

three-way socket (JIS B 2301).

(It is possible to attach three-way socket as option.)

2) The inside diameter of pipe size 20 to 32mm in 2MPa is based on

three-way socket (Sch.40). (Supplied by customer.)

3) 40mm or more, the inside diameter of in 1MPa specification is

based on Carbon steel tube for ordinary piping SGP (JIS G3452),

and the inside diameter of in 2MPa specification is based on

Carbon steel pipes for pressure piping STPG (JIS G 3454 Sch40).

4) 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). If you use other fittings, additional

calibration is needed. Please determine the values of “D” and

“L” in the figure at the end of this document and the kind of pipe

and then contact us.
