Wireless IC card ultrasonic large-diameter water meter

The wireless IC card ultrasonic large-diameter water meter is used in conjunction with a wireless ultrasonic large-diameter water meter and a large-diameter wireless IC card valve controller. There is no connection between the ultrasonic water meter and the controller, and they communicate wirelessly. Equipped with a remote meter reading system to achieve remote meter reading or on-site meter reading with a handheld device, making it convenient for users to control their meters.

1. Ultrasonic water meters use ultrasonic measurement to transmit data signals instead of pulse signals, fundamentally solving the problem of pulse accumulation caused by unstable pipeline water pressure, water hammer, and shaking, without worrying about strong magnetic attacks, and are stable and reliable.
2. Regularly remove dirt from low-frequency harmonics, automatically clean the transducer and reflector to ensure the accuracy of ultrasonic measurement. The wireless IC card ultrasonic water meter can periodically operate the valve according to the actual situation to remove water stains and scale, avoiding valve blockage and rust.
3. Powered by a 3.6V lithium battery and designed with ultra-low power consumption, the battery has a lifespan of over 8 years and is suitable for situations where AC power is not easily available.
4. It has prepaid and emergency functions. The user holding the purchase quantity of the user card can open the valve to supply water. Wireless IC card ultrasonic water meters can activate emergency functions in special circumstances and automatically switch emergency tonnage according to different caliber water meters to meet user needs.
5. It has infrared communication and wireless (non infrared) data exchange functions. The parameters of the wireless IC card ultrasonic water meter can be set through a handheld device. The controller and the meter can exchange data for multiple time periods, ensuring the reliability and timeliness of the information of the large-diameter wireless IC card ultrasonic water meter.
6. Historical data storage function. The wireless IC card ultrasonic water meter stores the monthly water usage for the past 18 months, making it convenient for users to keep track of their water usage. Historical record query function. Shake the card near the serial number of the meter to check the current time, water consumption for the current month, and historical records for the past 18 months.
7. Automatic settlement function. When the remaining amount in the wireless IC card ultrasonic water meter is less than or equal to 0, the valve will automatically close, and recharging can open the valve. Automatic warning function. The wireless IC card ultrasonic water meter can effectively identify based on wireless transmission data. Once data abnormalities occur, the valve will automatically close for warning. After the management department completes the inspection, it can be reactivated.
