The IC card ultrasonic heat meter integrates intelligent thermal energy measurement and prepaid control ball valve device. This product overcomes the shortcomings of ultrasonic heat meters that only measure without management, and also overcomes the current shortcomings of intelligent ball valves that only manage functions without measurement. The product has the characteristics of beautiful appearance, accurate measurement, convenient management, stable operation, strong anti pollution and anti-corrosion ability, long service life, safety, reliability, and economic practicality. It can be widely used in heating facilities for centralized heating management, household metering management, and prepaid management.

The IC card ultrasonic heat meter is based on the heat meter and adds functions such as on/off valve and card reading. It uses an RF card to transfer heat data and information bidirectionally between the heat meter and the heating management system, achieving heat metering and prepayment functions; After the user pays the fee to the management department, the management department writes the purchased heat value into the non-contact IC card. After the user inputs the data in the card into the table, the table automatically opens the valve for heating. When the purchased amount is used up, the table automatically closes the valve and stops heating.

Measurement accuracy: High quality transducers, Pt1000 high-precision platinum resistors, and advanced electronic measurement technology are used to ensure high accuracy and stability of flow measurement;

◆ Automatic descaling function: The valve is automatically opened and closed once a period to clean the sediment on the surface of the sphere using an IC card ultrasonic heat meter;

Switching valve torque: 3.2N · m (normal switching valve under dynamic water pressure of 1.2MPa);

Data remote transmission function: Remote meter reading and valve control can be achieved through M-Bus bus;

Strong anti-interference ability: not affected by impurities, chemicals, and magnetic materials in the medium;

Long service life: ultra-low power consumption design;

◆ Automatic error diagnosis function: In abnormal states, there is an error message prompt function to ensure safe and accurate operation;

◆ Protection function: Non contact IC card technology, sealed and waterproof;

Information protection function: One meter, one card, information is password protected, higher security;

◆ Automatic alarm function: When the remaining heat in the meter reaches the preset value, an automatic alarm will remind the user to purchase heat.
