| Abstract: | On analyzing the capability and principle of traditional elliptical gear flowmeter, a new-type high pressure, bi-directional elliptical gear flowmeter was presented, which utilized magneto-dependent sensors to measure the flows signal non-contactable. The finite element numerical simulation and experiments were carried out. The results showed that this new-type flowmeter could endure high pressure of 31.5 MPa, measure bi-directional flows, whose error was low, and high pressure loss was 0. 15 MPa and could be used in high pressure environment. |
