        Horizontal vane wheel, dry-dial cold (hot) water meter

        This type of water meter can be used for a remote reading transmission system as equipped with a built-in sensor.



        Application
        --Measuring the volume of cold (hot) water passing through the pipeline

        Feature:
        --Removable element structure, easy installation and maintenance;
        --Dry-dial, Magnetic drive;
        --Large flow capacity, small pressure loss;
        --Resist water hummer and pollution;
        --Vacuum sealed register ensures the dial keep free from condensation and keep the reading clear in a long term service;
        --Selected high quality materials for steady and reliable characteristic;
        --Technical data conform to international standard ISO 4064.
        Working condition
        Water temperature: 0.1℃~50℃ (0.1℃~90℃ for hot water meter)
        Water pressure: ≤1.0Mpa (1.6MPa on request)
        Maximum permissible errors

        in the lower zone from qmin inclusive up to but excluding qt is ±5%

        in the upper zone from qt inclusive up to and including qs is ±2% (±3% for hot water meter)
