Do you know the working principle of dry water meters?
The water pushes the impeller (the impeller is provided with magnetic steel, the impeller rotates and drives the magnetic steel to rotate) - the magnetic steel on the impeller drives the magnetic steel of the wheel box through the magnetic force the gear system changes speed --- the wheel rotates.
Dry water meter: counter is not immersed in the water meter, the structure of the sensor and counter of the chamber cavity phase separation, water meter glass is not subject to water pressure, sensor and counter transmission generally use magnetic steel transmission.
The water meter is divided into a wet type water meter, a dry type water meter and a liquid sealed water meter according to whether the counter is immersed in water.
For the output pulse meter, there is a wheel mounted on the magnet, the corresponding parts of the dry reed pipe or Holzer sensor, when the wheel drives the magnetic steel to rotate to the sensor position, the magnet magnetic sensor and a pulse.
