Abstract
A turbine meter for measuring the flow of a fluid comprises a housing having an inlet port and an outlet port and defining a fluid flow path along a central axis thereof. A flow conditioner is mounted in the flow path downstream of the inlet port and has a plurality of flow deflectors canted in a first direction relative to the central axis. A first turbine rotor is located downstream of the flow conditioner and is mounted for rotation about the central axis. The first turbine rotor has a plurality of first rotor vanes canted in a second direction relative to the central axis, the second direction being opposite to the first direction. The meter further comprises a second turbine rotor located downstream of the first turbine rotor and mounted for rotation about the central axis. The second turbine rotor has a plurality of second rotor vanes canted in the first direction relative to the central axis such that the first and second turbine rotors rotate in opposite rotational directions when fluid flows through the housing at rotational speeds indicative of fluid flow rate.
