Advantages Of Prepaid RF Card Water Meter

·Immersion sealing, can work in wet or underwater;
·The radio frequency card technology is adopted, which is convenient for users to operate;
·Pilot valve, free from scale and water pressure, more safe and reliable
·Generally, IC card water meter adopts ball valve, and valve opening and closing are easily affected by scale and water pressure. The ball valve ball and the outer wall will produce scale when they are immersed in water for a long time, which will increase the friction resistance, thus affecting the on-off valve; When the water pressure increases, the resistance of the ball valve will also increase exponentially, which will have a great impact on the opening and closing of the valve;
·The cork type working principle of the pilot valve is not affected by scale and water pressure;
·The pilot operated electric control valve with magnetic and hydraulic combination technology has low power consumption, and the valve can be opened and closed reliably and stably under low pressure.
·The base meter and valve adopt magnetic drive and special isolation seal design to solve the problem of dynamic seal and water leakage of ordinary IC card water meter.
·The ball of the ball valve is directly connected with the motor, and is generally sealed with a rubber ring. Over time, it is easy to age and deform, resulting in water leakage; The base meter and valve of Longkang IC card water meter adopt magnetic drive, and the isolation layer is reinforced and sealed with copper shell. The maximum pressure resistance can reach 35kg, and there will be no water leakage;
·Anti magnetic: When a magnetic object is close to the water meter, the water meter will automatically close the valve to prevent the magnetic object from interfering with the water meter metering;
