On all meters operating on gas measurement the casing of the meter is fitted with a burst disc. If
the primary seal (tube/s) fails leakage will occur from the burst disc. Install the meter so that the
burst disc is pointing away from personnel.
Regular maintenance of the burst disc: Regular maintenance of the burst disc: Regular maintenance of the burst disc: Regular maintenance of the burst disc:
Carry out regular maintenance checks on burst discs for leakage and/or blockages. On all
OPTIMASS meters, the primary seal is considered to be the measuring tube of the meter. The
materials of construction of the measuring tube/s are described within the relevant sections of
this handbook and the customer’s product and any other fluid flowing through the tube must be
compatible with the material of construction. If failure of the primary seal is suspected then the
process line should be de-pressurised and the meter removed as soon as it is safe to do so.
Please contact customer service for servicing or replacement of the meter.
