The present invention relates to a train control device of the Waltmann type water meter, in particular, to smoothly guide the flow of fluid from the fixed guide to the train control rotating wing to improve the train performance and to keep the train performance constant. It relates to a train control device of a Waltman water meter which is suitable.

In general, water meters are used to measure the passage volume of a fluid (eg water) passing through a pipeline to a measuring point, in particular a Waltmann water meter (a axial vane water meter) that spirals around the flow axis within the water meter. The blade car is rotated by the flow of the fluid, and the amount of the flow rate is indicated by indicating the total volume of the flow rate passed by the rotational speed.

In addition, in the water meter, a difference between the measured flow rate and the reference flow rate occurs, and a train control device is used to control the difference.

Such a train control device is registered, for example, a patent for improving the "train control device of water meter" according to the Republic of Korea Utility Model Registration No. 1997-0021041 and the "train control device of water meter" according to the 1997-0021041.
