●The example of standard specification

[example 1] Code number of CFIW2221 indicator with

Scale range 1 for 25, 50, 200, 300mm sizes has

[CFIW2221-25BD-□ 0-B].

Scales can be chosen. The graduation example is

shown in right drawing.

One piece of CFIW indicator is

able to have 4 different scale

ranges. But for the cases of

PVC lining pipe (option code:

/PL) and pipe with

non-standard inside diameter,

one indicator has one scale

range.

*1 PVC lining type is available for the size 32 mm to 150 mm as marked gray.

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, 32 mm size for 2 MPa class are shown in the

brackets in above table.

*3 The inside diameter of main pipe of 20 to 32mm in 1MPa class is based on

the three-way socket (JIS B 2301).(The three-way socket shall be attached

upon request.)

*4 The inside diameter of main pipe of 20 to 32mm 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 G3452) Carbon steel pipe for piping, and the inside diameter in

2 MPa class is based on the carbon steel pipe for STPG (JIS G 3454 Sch

40) for pressure piping.

● CFIW Indicator

The CFW2000 “ONE-TOUCH FLOW” is composed of :

- A CFIW indicator

- A CFNW fixing nozzle

- A three-way socket (for main pipe size 20 to 32 mm) or a socket for

welding piping (for main pipe size 40 mm or larger)

Note1

Example ① The combination of 4 measuring pipes:

The combined code of 4 measuring pipes for 25, 50, 200, 300 mm is “-25BD”.

The whole model code becomes “CFIW2□2□-25BD-□0-B

”.

Example ② The combination of 3 measuring pipes or less:

The combined code of 3 measuring pipes for 100, 125, 150 mm is “-89A0”.

The whole model code becomes “CFIW2□2□-89A0-□0-B

”.
