1. Wet water meter: It means that the counter of the water meter is immersed in water, and the surface glass of the water meter is subjected to water pressure. Dry water meter: The counter does not invade the water meter in the water. The sensor is technically isolated from the chamber of the counter, and the water meter glass does not bear water pressure.
2. In terms of measurement accuracy, there is no difference between a dry water meter and a wet water meter. Even if there is a difference, it is minimal,
3. After the wet water meter is used for a period of time (especially in areas with poor water quality), the dial is easy to turn yellow and black, which will affect the reading; if the surface glass of the water meter is broken, the water will overflow; when the temperature difference between the inside and outside of the meter is large, the glass It is easy to produce fog and water droplets on the surface, which will affect the reading; when the weather is cold, the water in the surface glass of the water meter will freeze (sometimes it will freeze the glass), which will make the water meter unable to work, or even damage the water meter.
4. In different use environments, we should choose different water meters correctly. For example, areas with softer water quality are more suitable for wet water meters, which are less prone to scale formation. In areas with hard water quality, because the water is prone to scale formation, and the dry water meter is isolated from the measured water due to counting, it will not affect the reading. Moreover, in cold weather conditions, the stability and safety of dry water meters are significantly higher than that of wet water meters.
