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 ow is in the same direction as shown by the arrow at the meter housing.
