What’s the prodcut and it’s working principle ?
Like the rotary vane wheel type (single jet &multi jet)Water meter (DN15-DN50), the Helix woltman type water meter belongs to one of the velocity type water meters. When the water flows into the water meter, the rotating speed of the impeller is proportional to the speed of the water flow. After the deceleration gear transmission, the total amount of water passing through the meter is displayed on the indicator device.wolman type water meter is divided into two categories: it can be divided into two categories: one is horizontal water meter and the other is vertical water meter. Most of the industrial meters used are horizontal type water meters. In addition, the detachable horizontal woltman water meter (dry type), thanks to it’s wide measuring flow range, strong versatility of parts and components, installation and maintenance can be carried out without stopping the water ,without disassembling the meter and so on, and has become a series of products among them. Be welcomed by users.
