Difference between dry water meter and wet water meterWhat are the advantages and disadvantages of the two water meters?
I think in the southern region, can give priority to the use of wet water meter, while in the north area, the priority should be given to dry water meter, because the dry water meter in the climatic conditions and the water is cold hard, working stability and security is significantly higher than the wet water meter
Dry water meter is not immersed in water meter counter, isolation chamber and counter sensor technology, water glass does not withstand the pressure. Because of the dry water meter counting mechanism and the measured water contact is not influenced by the suspended impurities in water, to ensure the normal work and counting mechanism of reading is clear; also not like wet the water meter, water meter reading of the phenomenon under the glass fog or condensed water droplets etc. the impact caused by the temperature difference between inside and outside the table; even in the process of using accidentally break the glass of water will not overflow, the safety is good.But because of the dry water meter structure is relatively complex, so the manufacturer's production technology and assembly process requirements are higher, so the cost is slightly higher than the wet water meter,
The counter wet water meter into water, after a period of time of use (especially the poor water quality in the area), the dial is easy to yellow, black, and meter reading effect; the surface of the glass to withstand the pressure, such as water surface of the glass is broken, the water will overflow. When large temperature difference, the glass is easy to produce fog effect of reading and water; when the weather is cold, the water surface in the glass of water will freeze (sometimes the glass burst) will make the water meter, unable to work, the direct damage of the water meter. But these phenomena only occur in many areas in the north of China, and in South China, almost no effect. And the initial amount of wet water meter have a dry water meter and is slightly smaller, because its structure is simple and the manufacturing cost of dry water meter, but also relatively small.
