Natural Soft Rubber, EPDM Rubber lining:
Internal insertion type
Ceramics lining: Integral type
Sanitary Type: Internal insertion type
Replaceable Electrode Type
Electrode parts can be put into unit to facilitate replace-
ment or mounting at customer site.
The optional dedicated tool (F9807SK) is required.
Replaceable electrodes are available for the
following:

Mounting/Shapes (Remote Flowtube):
• Electrical Connection: ANSI 1/2 NPT female
ISO M20 ϫ 1.5 female
JIS G1/2 (PF1/2) female
• Direction of Electrical Connection: The direction can be
changed even after delivery.
Note: In case of submersible types, an optional code DHC,
and sizes of 1100 mm or larger, the direction can not
be changed after delivery.
• Terminal Connection at Terminal Box: M4 size screw
Grounding:
Grounding resistance 100 Ω or less
* In case of explosion proof type except TIIS, follow the
domestic electrical requirements as regulated in each
country.
* In case of TIIS Flameproof type, refer to description of
“HAZARDOUS AREA CLASSIFCATION”.
Combined Converter:
• A remote flowtube for sizes of up to 400 mm can be
combined with the AXFA11 Converter or the AXFA14
Converter. If a combined converter is changed from
AXFA11 to AXFA14 or vice versa, a new meter factor
must be adjusted by flow calibrations.
• In case that size 250 mm (10 in.) or larger is used in low
conductivity or high concentration slurries, please use the
AXFA11 Converter.
• A remote flowtube for sizes of 500 mm or larger can be
combined with the AXFA11 Converter only.
• Maximum Cable Length:
Combination of AXF remote Flowtube and AXFA11:
up to 200 m (660 ft)
Combination of AXF remote Flowtube and AXFA14:
up to 100 m (330 ft)
■ HAZARDOUS AREA CLASSIFICATION
Refer to Chapter 8.
■ STANDARD PERFORMANCE
Accuracy
Note: The accuracy of a product before shipment is
defined as totalized value at the result of calibration
test in our water actual flow test facility.
Calibrated conditions in our water actual test facility
are as follows:
Fluid temperature; 20 ± 10°C
Ambient temperature; 20 ± 5°C
Length of straight runs;10 D or more on the
upstream side; 5 D or more
on the downstream side
Reference conditions; Similar to BS EN29104
(1993); ISO 9104 (1991)
