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.

Thermal shock
Thermal shock occurs when there is a sudden and extreme change (shift) in process
temperature. To avoid thermal shock, refer to the following table for the maximum temperature
shift.

CAUTION!
Operation outside these limits may result in shifts in density and mass flow calibration. Repeated
shocking may also lead to premature failure of the meter! However, higher thermal shocks are
possible at lower working pressures. For more information, please contact your nearest
representative.
