Beschreibung
Zusammenfassung:	A gas mass flow sensor for sensing a flow of compressed natural gas into an internal combustion engine is disclosed including a main flow passage having an inlet and an outlet forming a flow passage for the flow of compressed natural gas to the internal combustion engine, a secondary flow passage positioned within the main flow passage, a compressed natural gas flow sensor positioned within the secondary flow passage for sensing the flow rate of compressed natural gas through the secondary passage and a compressed natural gas flow conditioner for conditioning the flow of compressed natural gas through at least the secondary flow passage. The compressed natural gas flow conditioner includes a plurality of screening elements positioned substantially transversed to a direction of the flow of compressed natural gas through the flow sensor and a plurality of spacers for spacing each of the adjacent screening elements from one another.
