Pressure relief

ELITE sensors are available with a rupture disk installed on the case. Rupture disks are
meant to vent process fluid from the sensor case in the unlikely event of a flow tube
breach. Some users connect a pipeline to the rupture disk to help contain escaping process
fluid. For more information about rupture disks, contact Micro Motion Customer Service.
If the sensor has a rupture disk, it should remain installed at all times as it would otherwise
be necessary to re-purge the case. If the rupture disk is activated by a tube breach, the seal
in the rupture disk will be broken, and the Coriolis meter should be removed from service.
The rupture disk is located as follows on the meter, and the warning sticker shown is
placed next to it.
DANGER!
Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from the sensor
can cause severe injury or death.
The sensor must be oriented so that personnel and equipment will not be exposed to any
discharge along the pressure relief path.
Important
If a rupture disk is used, the housing can no longer assume a secondary containment function.
