3.6.4 Higher temperature applications and sensor insulation
best practices
Insulation of the magnetic flowmeter sensor is not typically recommended. However, in
applications with higher temperature process fluids (above 150°F / 65°C), plant safety, sensor
reliability, and sensor longevity can be improved with careful attention to proper insulation.
1. In applications where process fluid permeation of the liner has been observed or may
be expected, the rate of permeation can be reduced by decreasing the temperature
gradient between the process fluid and the outside of the meter body. In these
applications only the space between the process flanges and the coil housing should
be insulated (see Figure 3-16).
