If a sensor is installed horizontally with a curved measuring tube, match the position of the
sensor to the fluid properties.

Orientation of sensor with curved measuring tube
1
Avoid this orientation for fluids with entrained solids: Risk of solids accumulating.
2
Avoid this orientation for outgassing fluids: Risk of gas accumulating.
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.

Requirements from environment and process
Ambient temperature range
Measuring device
–40 to +60 °C (–40 to +140 °F)
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.
