3.2 Nameplates
3.3 CSA Dual Seal
To comply with the requirements of ANSI/ISA -12.27.01-2003 “Requirements for process Sealing
Between electrical systems and Flammable or Combustible process Fluids” a secondary seal is
incorporated into all OPTIMASS / GAS products. If the primary seal fails, the secondary seal will
prevent escaping fluid reaching the electronic compartment.
Pressures and / or temperatures are limited by tube, temperature, connection and Ex limits.
Check the meter nameplates and relevant documentation for full details. On all meters
operating on gas measurement, the casing of the meter is fitted with a burst disc. If the primary
seal (tube) fails leakage will occur from the burst disc. Install the meter so that the burst disc is
pointing away from personnel.

OPTIMASS 3000 / 3300 / 3010 -40°C...+150°C and 100...14000 kPa
Pressures and/or temperatures may be further limited by tube, temperature, connection and Ex
limits. Consult the meter nameplate and relevant documentation for full details.
If the primary seal fails, the casing of the meter will fill with liquid and the meter will stop
working. The meter will notify the operator by going into mode and a diagnostic error
will be shown on the converter or PLC display. This is an indication that the primary seal (tube)
has failed and the status of the meter should be checked.
Meter status: Meter status: Meter status: Meter status:
The meter will also go into mode if the primary seal (tube) fails, or if they are not
completely filled with fluid. For example, if the meter is drained or re/filled.
To check the status of the meter, drain and re/fill with fluid and note the converter or PLC
display. See the relevant section of the converter handbook for a list of status messages and
diagnostics information.
If the meter remains in mode you MUST assume that the primary seal (tube) has failed
and the appropriate action MUST be taken.
