Product Introduction
Woltman water meter, is a kind of speed type water meter, suitable for use in large caliber pipeline (DN80-DN200), which is characterized by large circulation capacity and small pressure loss. When the water flows into the water meter, along the axis of the direction of the impact of the water meter screw-wing shaped impeller rotating out, the impeller's rotational speed is proportional to the speed of the water flow, after the reduction gear transmission, the total amount of water passing through the water meter is displayed on the indicator device.
