Should You Choose a Dry or Wet Water Meter for Your Home?
I. Core Differences
Wet Water Meter: The movement is directly immersed in water. The water flow drives the impeller, which in turn drives the counter via gears.
Dry Water Meter: The movement is sealed and isolated, not in contact with water. A magnetic drive transmits the impeller's rotation signal to the counter.
II. Key Differences
1. Reading Clarity
Dry Water Meter: No scale or fogging on the inside of the glass; the numbers are always clear. Suitable for poor water quality or backlit environments.
Wet Water Meter: Susceptible to water quality and temperature differences; may become blurry after long-term use, requiring frequent wiping.
2. Durability and Lifespan
Dry Water Meter: The movement is not corroded by water, with a lifespan of 8-10 years. Suitable for areas with poor water quality or large water pressure fluctuations.
Wet water meters: The movement is prone to jamming or rusting due to impurities, with a lifespan of approximately 6-8 years. Water quality maintenance is required.
3. Metering Accuracy
Dry water meters: Less affected by water quality and pressure, more stable in high-rise buildings or areas with large water pressure fluctuations.
Wet water meters: Accuracy meets standards under normal water usage, but may deviate when impurities or abnormal water pressure occur.
4. Price
Wet water meters: Simple structure, lower price, suitable for budget-constrained scenarios or scenarios with good water quality.
Dry water meters: Due to their sealed design and magnetic transmission, the price is slightly higher (20%-30%).
III. Applicable Scenarios
1. Prioritize dry water meters: Areas with poor water quality and many impurities.
High-rise buildings or areas with large water pressure fluctuations.
Seeking long-term stable readings and low maintenance costs.
2. Prioritize wet water meters: Environments with good water quality and stable water pressure.
Limited budget and installation in a dry indoor location.
Outdoor water meters (with proper insulation and anti-freezing measures).
