Intended use
1.3.1
Purpose of the device
The FLOWSIC100 Flare measuring system may only be used for measurements of gas
velocity, gas volume, mass flows and molecular weight in pipelines.
1.3.2
Correct use
1.3.2.1
General
Use the device only as described in these Operating Instructions. The manufacturer
bears no responsibility for any other use.
Observe all measures necessary for conservation of value, e.g. for maintenance and

– the device could become dangerous
– any warranty by the manufacturer becomes void
⊗
Do not use damaged components or parts.
1.3.2.2
FLSE100 sender/receiver units for use in ex zones
The sender/receiver units of the FLOWSIC100 EX-S, EX, EX-RE and EX-PR device versions
are available as options for use in Ex zone 1 and 2 or as versions for use in Ex zone 2 only.
1.3.2.3
Use of FLOWSIC100 FLARE depending on temperature class and process temperature
Installation and use of sender/receiver units FLSE100 where electronic parts and
transducer parts are in the same area
This area is a hazardous area, i.e. zone 1 or zone 2 in which an explosive atmosphere exists
under normal atmospheric conditions of:
– specified ambient temperature -40 ... +70 °C for T4 or -40 ... +55 °C for T6,
optionally minimum ambient temperature -50 °C
– ambient pressure 80 kPa (0.8 bar) to 110 kPa (1.1 bar)
– air with normal oxygen content, typically 21 % v/v.
●
Sender/receiver units marked ATEX II 2 G IECEx and CSA Class I Division 1
are approved for use for gases in Ex zones 1 and 2.
●
Sender/receiver units marked ATEX II 3 G and CSA Class I Division 2 are
suitable for use for gases in Ex zone 2.
