Tandem Rotor Turbine Meter And Field Calibration Module

US Patent:
5473932, Dec 12, 1995
Filed:
Sep 22, 1993
Appl. No.:
8/125344
Inventors:
James J. Fitzpatrick - DuBois PA
Daniel W. Peace - Punxsutawney PA
Assignee:
M & FC Holding Company, Inc. - Wilmington DE
International Classification:
G01F 2500, G01F 700
US Classification:
73 3
Abstract:
Methods and an apparatus for measuring gas flow with greater reliability than earlier single-rotor and double-rotor turbine meters and dual turbine meter systems are disclosed. The apparatus comprises two independent rotors, in close proximity of each other, housed in the same meter body, but isolated from the effects of each other. No pressure and temperature correction are needed for accuracy performance comparison between the two rotors. Because of the two rotor averaging technique, the reliability of the volume totalization is greatly improved over earlier double-rotor and single-rotor designs.
