Product Introduction
Small-diameter residential rotor water meter: utilizes a single water flow stream to drive the impeller, employs magnetic coupling transmission, and features a completely isolated (dry-type) counter. The magnetic field drives the impeller to rotate, which in turn actuates the dial counter above; this device belongs to the category of magnetic-transmission dry-type water meters and complies with the national standard GB/T 778. Key advantages include: clear readings—due to the dry counter design, the inner surface of the glass dial does not fog, condense, or develop algae; resistance to freezing in low-temperature environments; simple structure, compact size, light weight, low manufacturing cost, and minimal installation space, making it ideal for replacement in confined indoor areas. Single-flow design: only one water stream drives the impeller, resulting in minimal pressure loss; integrated filter mesh to block large particulate impurities; expandability—base units can be equipped with pulse or photoelectric modules, and upgraded versions support remote transmission or NB-IoT connectivity. Anti-magnetic structure available to resist interference from external magnets and prevent water theft. ✅ Basic Technical Parameters (Standard Cold Water Model): Installation: Horizontal mounting; Nominal pressure: ≤1.0 MPa (10 bar), with some models supporting up to 1.6 MPa; Cold water: ≤30 °C; Hot water: up to 90 °C; Metering grade: primarily Class B, with Class C available for high-end applications; Range ratio: R80/R100/R160; Accuracy: ±2% for typical flow rates; ±5% for minimum flow rates (Class B). ✅ Applicable Scenarios: Individual household metering in residential buildings, rental properties, and small commercial premises; suitable for tap water with relatively clean quality.
