Described deceleration stem A circumferentially evenly distributes along gearcase, and the height of deceleration stem A is 3～4mm.
Described deceleration stem B circumferentially evenly distributes along impeller box, and the height of deceleration stem B is 3～4mm.
Described water inlet circumferentially evenly distributes along impeller box, and the horizontal section of water inlet is a rectangle, and the distance of water inlet distance impeller box center line in parallel is 18～19mm.
Described water delivering orifice circumferentially evenly distributes along impeller box, and the horizontal section of water delivering orifice is a rectangle, and the distance of water delivering orifice distance impeller box center line in parallel is 15～16mm.
The present invention has the following advantages: water inlet of the present invention is set to rectangle; And the distance of the impeller box center line that the water inlet distance is in parallel is 18～19mm; Increased the impulsive force of fluid to impeller; In the time of can guaranteeing that even discharge is very little, current also can directly get into cavity and promote wheel rotation, thereby realize measuring more low discharge; Be respectively equipped with deceleration stem B and deceleration stem A on the bottom surface B of impeller box cavity and the gearcase bottom surface A; Deceleration stem B and deceleration stem A adjust wheel speed when impeller is rotated by water impact; Realize the accurate measurement of each flow point; Thereby improved the precision of water meter measurement, the ratio of Q3/Q1 can reach more than 160; Fluid is more unobstructed thereby the design that four water delivering orifices are uniformly distributed with has increased the sectional area of water delivering orifice when having guaranteed big flow.
