ABSTRACT:
A gas turbine meter includes a measuring cartridge which has a measuring rotor that rotates in one direction at a speed approximately proportional to the velocity of gas flowing through the meter and a reference rotor mounted downstream of the measuring rotor which rotates in the opposite direction from the measuring rotor. An inlet flow straightener upstream of the measuring rotor causes gas to flow substantially axially within the meter, and a reference flow straightener mounted between the measuring rotor and the reference rotor also causes gas to flow substantially axially within the meter. The inlet flow straightener and the reference flow straightener are constructed so that a measurement of the accuracy of the meter can be conducted without measuring differences in pressure and temperature between the locations of the measuring rotor and the reference rotor. A signal processor provides an indication of the accuracy of the gas turbine meter based on the quotient of a measuring signal, which is proportional to the speed of rotation of the measuring rotor, divided by a reference signal, which is proportional to the speed of rotation of the reference rotor.
