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)

Observe maximum permitted ambient temperature for the transmitter .
‣
Depending on the fluid temperature, take the device orientation requirements into
‣
account .
NOTICE
Danger of overheating when heating
Ensure that the temperature at the lower end of the transmitter housing does not
‣
exceed 80 °C (176 °F).
Ensure that sufficient convection takes place at the transmitter neck.
‣
Ensure that a sufficiently large area of the transmitter neck remains exposed. The
‣
uncovered part serves as a radiator and protects the electronics from overheating and
excessive cooling.
When using in potentially explosive atmospheres, observe the information in the
‣
device-specific Ex documentation. For detailed information on the temperature tables,
see the separate document entitled "Safety Instructions" (XA) for the device.
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

Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions→ 172. Therefore, a zero point
adjustment in the field is generally not required.
Experience shows that zero point adjustment is advisable only in special cases:
• To achieve maximum measuring accuracy even with low flow rates.
• Under extreme process or operating conditions (e.g. very high process temperatures or
very high-viscosity fluids).
