Reference conditions

3.4.11 Purge ports

If the meter has been ordered with a purge port, it will be supplied with NPT female connections
which are clearly marked. The connections are sealed with NPT plugs and PTFE tape.

3.4.12 Burst discs

If the meter has been ordered with a burst disc, it will be supplied with the disc fitted. The failure
pressure of the disc is 20 barg at +20°C / 290 psig at +68°F.

Automatic fitment

If the connection rating of the meter is greater than 100 barg / 1450 psig but the 150 barg / 2175
psig secondary containment option has not been purchased, the meter will be supplied with a
burst disc fitted as a safety feature.

Ambient temperature

+25°C / +77°F

Heating medium

Hot liquid

Heating medium temperature

+130°C / +266°F

CAUTION!
DO NOT remove these plugs.

The meter is factory sealed with a dry nitrogen gas fill and if moisture is allowed to enter the
meter casing it will cause damage. The plugs should only be removed to purge the meter casing
in the event that the primary measuring tube fails.

If it is suspected that the primary measuring tube has failed, de-pressurise the meter and
remove it from service, as soon as it is safe to do so.

CAUTION!
The fitted burst disc will be suitable for the flow rates and process conditions specified on the
original order. If the process conditions alter in any way, it is recommended that you contact the
manufacturer for advice regarding suitability.

If the process product is hazardous (in any way) it is recommended that an exhaust tube is
connected to the NPT male thread of the burst disc and the pipe routed so that the process
product can be discharged to a safe area. Use a tube with a diameter large enough AND routed in
such a way, so that pressure cannot build up in the meter case.
