Document Type and Number:
WIPO Patent Application WO/2010/023995
Kind Code:
A1
Abstract:
An axial flow positive displacement flowmeter capable of reducing pressure loss, manufacturable at low cost, and having high accuracy. The axial flow positive displacement flowmeter (1) comprises a pair of rotors (10) of a same shape and a same size with different torsional directions, a casing (4) in which the rotors (10) are housed, an inlet side cover (2) for sealing the inflow side end of the casing (4), an inlet port (21) formed in the flange (22) of an inlet side cover (2), an outlet side cover (3) for sealing the outlet side end of the casing (4), and an outlet port (31) formed in the flange (32) of the outlet side cover (3). The inlet port (21) and the outlet port (31) are arranged in alignment with each other along the flowing direction of a fluid to be metered.
