Temperature Of Medium - ABB FV4000 Operating Instruction

12.9 Temperature of medium

Important
Please note the information in the section titled "Explosion
protection".
Compliance with the permissible temperature range for the
gaskets is mandatory.

12.10 Flowmeter insulation
The pipeline may be insulated up to a maximum of 100 mm (4 inch)
upper edge.
Use of trace heating
Trace heating may be used under the following conditions:
• If it is fixed directly on or around the pipeline
• If, in the case of existing pipeline insulation, it is installed inside
the insulation (the maximum height of 100 mm (4 inch) must not
be exceeded)
• If the maximum temperature the trace heating is able to produce
≤ the maximum temperature of the medium
The requirements to be met by integrators set out in EN 60079-
14 must be complied with!
Please note that the use of trace heaters will not impair EMC
protection or generate additional vibrations.

) For the supply circuit (terminals 31 / 32) and the switching outputs 41 and 42,
cables suitable for temperatures up to T = 110 °C (230 °F) may be used without
restriction. Cables which are only suitable for temperatures up to
T = 80 °C (176 °F) restrict the temperature ranges. These restrictions also
apply to the VR version (remote design) and the PROFIBUS PA design with
plug connector.
Important
The legibility of the display can be impaired at temperatures
< 0 °C (< 32 °F) and > 55 °C (> 131 °F). The functionality of
the meter and the outputs remains unaffected by this. Please
refer to the order information for ambient temperatures < -
20 °C (< -4 °F).
