3.3 Assembly into gas meter
Sensirion delivers SGM70xx modules only (see the images below only for illustration purposes, design-in is customer’s own
responsibility). Dimensions are given in mm.
The SGM70xx module is held in place by an O-ring and a metal fixation clip. The O-ring and the fixation clip are not supplied
by Sensirion.
Note: the correct function and performance of the SGM70xx module depends on the design and assembly of the gas meter
housing. Sensirion AG provides specialized consulting for the integration of SGM70xx into the customer-specific gas meter
housing.
3.3.1 Mounting place
SGM70xx modules are designed to be placed at gas meter outlet.
3.3.2 Mesh at SGM module
Sensirion recommends including a mesh at the outlet (and preferably also at the inlet) of the gas meter to prevent large
particles (e.g. screws or nuts) from entering the meter housing.
3.3.3 Mounting restrictions
During or after assembly of the gas meter mechanical stress to SGM70xx module has to be avoided. The mounting has to be
in a way that constant gas intake conditions are guaranteed.
3.3.4 Mounting orientation
Recommended vertical, with upwards flow. Connector PINs oriented towards inlet port. Other mounting orientations are
possible. For more information please contact Sensirion.
3.4 SGM70xx Housing Material
Plastic: PBT (polybutylene terephthalate)
