1) Applications with low process temperatures may reduce the ambient temperature. To maintain the
minimum ambient temperature for the transmitter, this orientation is recommended.
2) Applications with high process temperatures may increase the ambient temperature. To maintain the
maximum ambient temperature for the transmitter, this orientation is recommended.
Inlet and outlet runs
No special precautions need to be taken for fittings which create turbulence, such as
valves, elbows or T-pieces, as long as no cavitation occurs (  19).

6.1.2 Requirements from environment and process
Ambient temperature range
Measuring device • –40 to +60 °C (–40 to +140 °F)
• –50 to +60 °C (–58 to +140 °F) (Order code for "Test, certificate", option JM
Safety Barrier Promass 100 –40 to +60 °C (–40 to +140 °F)
‣If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
System pressure
It is important that cavitation does not occur, or that gases entrained in the liquids do not
outgas.
Cavitation is caused if the pressure drops below the vapor pressure:
• In liquids that have a low boiling point (e.g. hydrocarbons, solvents, liquefied gases)
• In suction lines
‣Ensure the system pressure is sufficiently high to prevent cavitation and outgassing.
For this reason, the following mounting locations are recommended:
• At the lowest point in a vertical pipe
• Downstream from pumps (no danger of vacuum)

Heating
NOTICE
Electronics can overheat due to elevated ambient temperature!
‣Observe maximum permitted ambient temperature for the transmitter (  19).
‣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.
6.1.3 Special mounting instructions
Outlet run for peripheral device
If a pressure and temperature measuring device are installed downstream from the
measuring device, make sure there is sufficient distance between the two devices.

Guarantees complete drainability
When the sensor is installed in a horizontal line, eccentric clamps can be used to ensure
complete drainability. When the system is pitched in a specific direction and at a specific
slope, gravity can be used to achieve complete drainability. The sensor must be mounted in
the correct position to ensure full drainability in the horizontal position. Markings on the
sensor show the correct mounting position to optimize drainability.
