Heating
NOTICE
Electronics can overheat due to elevated ambient temperature!
‣
Observe maximum permitted ambient temperature for the transmitter (→ 20).
‣
Depending on the fluid temperature, take the device orientation requirements into
account .
Heating options
If a fluid requires that no heat loss should occur at the sensor, users can avail of the
following heating options:
• Electrical heating, e.g. with electric band heaters
• Via pipes carrying hot water or steam
• Via heating jackets
Using an electrical trace heating system
If heating is regulated via phase angle control or pulse packages, magnetic fields can affect
the measured values (= for values that are greater than the values approved by the EN
standard (sine 30 A/m)).
For this reason, the sensor must be magnetically shielded: the housing can be shielded
with tin plates or electric sheets without a privileged direction (e.g. V330-35A).
The sheet must have the following properties:
• Relative magnetic permeability µr ≥ 300
• Plate thickness d ≥ 0.35 mm (d ≥ 0.014 in)
Vibrations
The high oscillation frequency of the measuring tubes ensures that the correct operation of
the measuring system is not influenced by plant vibrations.

Special mounting instructions
Rupture disk
Make sure that the function and operation of the rupture disk is not impeded through the
installation of the device. The position of the rupture disk is indicated on a sticker beside it.
For additional information that is relevant to the process (→ 105).
The existing connecting nozzles are not designed for a rinse or pressure monitoring
function.
