Mass flow rate recording device for an internal combustion engine's intake section, inserts in a main pipe with mass flow passing along it in a full flow direction

摘要

Mass flow passes along a main pipe (1) in a full flow direction (10). An auxiliary pipe (5) fits in a mass flow rate gauge (2) with a casing (3) and inlet (4) and outlet (6) openings. A sensor (7,8) fits in the auxiliary pipe. The mass flow rate gauge inserts in the main pipe.
