Gammapilot M FMG60 with FOUNDATION Fieldbus Installation
Endress+Hauser 21
3.3.2 Required flow rate
The required flow rate depends on
• the ambient temperature at the water cooling jacket
• the inlet temperature
• the measuring range of the Gammapilot M
Typical values are given in the following tables:
Ambient temperature T
A
=75°C
Ambient temperature T
A
=100°C
Ambient temperature T
A
=120°C
3.4 Post-installation check
After installing the device, carry out the following checks:
• Is the device damaged (visual inspection)?
• Does the device correspond to the measuring point specifications for ambient temperature,
measuring range etc.?
• If available: Are the measuring point number and labeling correct (visual inspection)?
• Is the measuring device sufficiently protected against direct sunlight?
• Are the cable glands tightened correctly?
