Requirements from environment and process

Ambient temperature range

Local display
Sensor
‣
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 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)
Thermal insulation
In the case of some fluids, it is important to keep the heat radiated from the sensor to the
transmitter to a low level. A wide range of materials can be used for the required
insulation.
