The main elements of the counting mechanism: a set of gears, drums and the counter housing. The mechanism is attached to the body with a mounting ring which is sealed after the verification process. Meter rotor is powered by the water flow pushing it around the perimeter. Counter adds the volume of water measured. The control device is protected from tampering with the seal. Thanks to the special design of the rotor bearings and the selection of quality materials, resistant to corrosion and abrasion, we manage to achieve high durability of the water meter.
