·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;

This product is a dual power supply system composed of a solar power distribution system and a battery powered electromagnetic flowmeter. Under the condition of solar energy, the solar power supply can achieve flow measurement, data wireless upload and flow control. In the absence of solar energy, the battery power supply system can complete flow measurement and data wireless upload. This system is especially suitable for flow measurement and flow control in oil fields without power supply.Product Functions and Features:The solar power distribution system has solar protection, over-current, over-voltage protection and other functions, which can ensure the long-term reliable use of solar panels and batteries.The self-developed solar power distribution system outputs two 12V low-noise power supplies, ensuring high-precision measurement of electromagnetic flowmeter. It is equipped with battery powered converter of our company, and can operate continuously for more than 14 days.The valve control and drive power in the embedded control valve can ensure reliable operation of the valve.The combination of the solar dual power supply flow measurement system and the solar power supply valve actuating system can realize the solar dual power supply flow control system, whose control flow setting value can be set remotely, and supports remote control of valve opening and closing.The wireless data transmission system supports 4G, NB, Zigbee wireless data transmission networks, and can transmit instantaneous flow, cumulative flow, alarm status and control parameters (specially customized).
