The gas should be dry. If condensate may be occur then the installation
of a condensation trap upstream of the meter is recommended
(in some filter types it is integrated). In this case choose
o
Flow direction from top to bottom
o
Do Not install the meter at the lowest point of the piping
Attention:
The MQM Quantometer is not suitable for oxygen and other highly
corrosive gases as well as for explosive gases and gas mixtures.
8. Mounting Position / Direction of Flow
There are two positions of installation possible for the turbine gas meter:
Horizontal installation or vertical installation
Figure 2: Typical horizontal installation of the MQM Quantometer (recommended)
Figure 3: Typical vertical installation of the MQM turbine gas meter (only DN ≤ 150)
Notice:
Ensure that the gas flow is in the same direction as shown by the arrow at the meter housing.
