A dry-type water meter refers to a water meter where the counter (dial) does not come into contact with the water being measured. Its transmission mechanism and counting gears are completely sealed in an independent dry chamber, and the movement of the water flow is transmitted to the counter through the magnetic steel coupling transmission method.
The core feature is that "water flows along its own path and characters follow theirs", with the two being completely isolated.
This is the key to understanding dry-type water meters:
| Feature | Dry-type water meter | Wet-type water meter |
|---|---|---|
| Counter environment | Dry air, isolated from water. | Immersed in water, in direct contact with water. |
| Transmission method | Magnetic steel coupling (non-contact). | Gear direct meshing (impeller shaft directly passes through the sealing ring to drive the counter). |
| Readability clarity | Excellent, not affected by water quality. | May be blurred, easily affected by scale, bubbles, and impurities. |
| Low flow sensitivity | Higher (less rotational resistance). | Lower (friction at the shaft seal). |
| Sensitivity to external magnetic interference | Sensitive (disadvantage). | Insensitive (advantage). |
| Structural complexity | More complex, higher cost. | Simpler, lower cost. |
| Mainstream application | Preferred choice for modern residential and commercial applications. | Still used in scenarios with clear water and low readability requirements, or in special industrial settings. |
| Freezing resistance | Better (no ice formation on the dial). | Poor (water freezing can damage the dial). |
Dry-type water meters, with their core design of magnetic coupling transmission and water-digit separation, have perfectly solved the problems of blurred readings and easy contamination of traditional wet-type water meters. They have significant advantages in reliability, readability and intelligent expansion. They have become the standard configuration and basic hardware in the modern water supply metering field, especially during the transition to smart water management. The vast majority of the base meters of the Internet of Things (IoT) smart water meters we see in our daily lives and those that will be deployed on a large scale in the future are based on dry-type or liquid-sealed structures.
