Applicable Bulidings: apartment, business district, community, village, hotel, rental house and school
The main technical parameters of the ICk card prepaid water meter are:
(1) Water temperature: This parameter specifies the maximum temperature used by the water meter. Users should choose appropriate models and specifications to meet their own needs, otherwise it will cause the water meter to measure the total water flow inaccurately.
(2) Working pressure: It specifies the maximum pressure of the metered water body. Water pressure exceeding this limit may damage or leak the water meter.
(3) Flow coefficient: It includes nominal diameter, maximum flow, nominal flow, boundary flow, minimum flow, and starting flow. Users can choose the nominal diameter and nominal flow according to practical needs. The starting flow reflects the sensitivity of the water meter.
(4) Indication error.
(5) External dimensions and weight: The external dimensions of the water meter include various parameters that need to be understood during installation, such as length, width, height, and connecting threads. In addition, the size and weight are related to packaging and transportation.
