Dry type water meters have counting mechanism isolated from the water, which make them get rid of floating impurities. They can ensure the counting mechanism work normally and give out clear numbers, not influenced by mist or condensing drops under the glass caused by temperature difference inside and outside of the meters.
1. The countering part is not immersed in water, so the glass cover does not bear water pressure.
2. Even if the glass is accidentally broken, the water will not overflow
Application advice
The stability and safety of dry-type water meters in colder climates and areas with worse water quality are significantly higher than those of wet-type water meters.

Product features
1) The use of a bottom-opening, spiral-structured battery sealing compartment can not only ensure reliable sealing, but also facilitate replacement.
2) Since the life of the electronic part is more than 10 years, but the battery life cycle is 6 years, by replacing the battery, the user's cost can be greatly reduced.

1) The measuring mechanism of wet-type water meter is driven by magnetic elements and the measuring part does not contact the water to be measured.
2) The counting mechanism of the dry-type water meter is isolated from the measured water, it is not affected by the suspended impurities in the water, ensuring the normal operation of the counting mechanism and clear readings.
3) The reading of the water meter will not be affected by fogging or condensation under the glass due to the temperature difference between the inside and outside of the meter.
Dry-type water meters should be installed where free of magnet.
The Dry-type water meters ensures clear data reading and effective working mechanism in winter or colder surroundings, which will keep the price of water consumption unchanged.
1) One of the major characteristics of dry-type water meters is that they are more waterproof and frost-resistant.
2) There is no water in the dry-type water meter counter, so the glass cover will not be affected by water pressure.
Yes, they could be replaced by users once the battery is out of energy.
3.6V lithium battery model ER26500.
The standby average current ranges from 25μA to 30μA.
