interconnecting cable between transmitter and
sensor is 152 m. The cable shall also be provided by
Rosemount Inc., or by Emerson Process Management
Flow Technologies Co., Ltd.
2. Suitable heat-resisting cables rated at least +80 °C
shall be used when the temperature around the cable
entry e60 °C.
3. Dimensions of flameproof joints are other than the
relevant minimum or maximum specified in Table 3 of
GB3836.2-2010. Contact manufacturer for details.
4. The Flowmeter is provided with special fasteners of
property class A2-70 or A4-70.
5. Any friction should be prevented in order to avoid the
risk of electrostatic charge on the enclosure due to
non-conductive paint.
6. The earthing terminal should be connected to the
ground reliably at site.
7. Do not open when energized.
8. The cable entry holes have to be connected by means
of suitable entry device or stopping plugs with type of
protection of Ex d IIC Gb the cable entry device and
stopping plugs are approved in accordance with
GB3836.1-2010 and GB3836.2-2010, and which are
covered by a separate examination certificate, any
unused entry hole is to be fitted with type of
protection of Ex d IIC Gb flameproof stopping plug.
9. Users are forbidden to change the configuration to
ensure the explosion protection performance of the
equipment. Any faults shall be settled with experts
from the manufacturer.
10. Precautions shall be taken to ensure that the
electronic parts are within permissible ambient
temperature considering the effect of the allowed
fluid temperature.
11. During installation, operation and maintenance, users
shall comply with the relevant requirements of the
product instruction manual, GB3836.13-1997
“Electrical apparatus for explosive gas atmospheres
Part 13: Repair and overhaul for apparatus used in
explosive gas atmospheres”, GB3836.15-2000
