5.1.7 Sensor insulation
Fig. 14: Insulation of the meter tube
1 Insulation
The piping can be insulated up to a thickness of 100 mm
(4 inch).
5.1.8 Use of trace heating
Trace heating may be used under the following conditions:
— If it is installed directly on or around the piping
— If, in the case of existing pipeline insulation, it is installed
inside the insulation (the maximum thickness of
100 mm [4 inch] must not be exceeded)
— If the maximum temperature the trace heating is able to
produce is less than or equal to the maximum medium
temperature.
NOTICE
The installation requirements set out in EN 60079-14 must be
observed.
Please note that the use of trace heaters will not impair EMC
protection or generate additional vibrations.
