1.3.3
Operation in potentially explosive atmospheres
1.3.4
Operation in pressure applications
Design, manufacture and inspection of the FLOWSIC30 measuring system is performed in
compliance with the safety requirements set forth in the ASME standard B31.3.
1.3.5
Operation in applications with wet gas
FLOWSIC30 has been designed for robust and reliable operation in challenging gas produc -
tion applications. In these applications, wet gas may also be existent in the gas stream.
However, FLOWSIC30 is a gas meter. All specifications of the gas meter apply for dry gas
only. Any wet gas in the gas stream may adversely affect the certainty of the measured
values and meter function.
→ Fig. 2 shows the gas meter's operating range at low pressure in horizontal and in vertical
meter orientation. Horizontal installation of the gas meter is recommended for wet gas
applications.
Since the effects of 2-phase streams with mixtures of liquid and gas are very complex, a
general operation guarantee cannot be given for the gas meter in these conditions.

The FLOWSIC30 is suitable for use in potentially explosive atmospheres:
IECEx: Ex db eb ia [ia] IIA T4 Gb
ATEX: II 2G Ex db eb ia [ia] IIA T4 Gb
