<p>An elliptic-gear flow meter with four magnetic steels comprises two elliptic gears (3, 4), wherein two magnetic steels (5, 6; 7, 8) are built in each of the elliptic gears (3, 4) respectively, such that the total number of the magnetic steel is four, and the two magnetic steels of each of the elliptic gears correspond to one magneto-dependent sensor (9, 10), hence the number of the induced pulse signal for each revolution of the elliptic gear is four and the measuring accuracy of the elliptic-gear flow meter is improved.</p> |
