B Rupture Disk
Using the rupture disk
The primary reason for having a rupture disk is to vent process fluid from
inside the sensor case, should the sensor flow tube rupture in a high-
pressure application. Some users, such as those measuring high-
pressure gases, install a pipeline at the rupture disk fitting, to help
contain escaping process fluid. This provides additional protection
should a rupture occur.
