IC card cold water meter is composed of remote water meter, controller and solenoid valve. The main control parameters selected for the water meter are flow rate, common flow rate, overload flow rate, minimum flow rate, cut-off flow rate, nominal pressure, maximum allowable working pressure, pressure loss, etc.
According to the combination of controller and solenoid valve, it is divided into: integrated IC card cold water meter, and split IC card cold water meter.
According to the structure of the wing wheel, it is divided into: screw-type IC card cold water meter and rotor-type IC card cold water meter.
According to the different immersion methods of counting devices, it is divided into: dry IC card cold water meter and wet IC card cold water meter.
IC card cold water meter construction and installation:
1) The water meter should be installed in a place that is convenient for maintenance and reading, and is not exposed to exposure, freezing, pollution and mechanical damage.
2), IC card water meter is composed of remote water meter, controller and solenoid valve. According to the combination of the controller and the solenoid valve, there are two installation methods for the IC card water meter: one is to seal the controller and the solenoid valve in a control box and install it directly on the pipeline together with the water meter; the other is to control the water meter. The solenoid valve and the solenoid valve are arranged separately. The solenoid valve is installed on the pipeline behind the water meter, and the controller is installed in a suitable position according to the requirements of convenience or indoor decoration and arrangement.
3), IC card water meter is only suitable for the measurement of tap water, not for wastewater and industrial sewage.
4) When choosing the model of IC card water meter, pay attention to the direction of water flow to avoid inconvenience of installation.
5) The IC card water meter should be installed as horizontally as possible, with the dial upward, and the direction of the arrow consistent with the direction of the water flow.
