Non contactlCcardUltrasonic heat meterUsing ultrasonic flow measurement technology, it is used to measure and display the heating capacity of household users, and also has a prepaid function. The user pays the heating fee to the management department, and the management department writes the purchased heat value into itICIn the card, the user willICAfter entering the information in the card into the heat meter, the heat meter automatically opens the valve for heating. During the user's use, the microcomputer in the heat meter automatically reduces the remaining amount. After the purchased heat is exhausted, the heat meter automatically closes the valve and stops heating. The user needs to purchase heat again and swipe the card before opening the valve for heating. This table can also be used as an instrument for measuring cooling capacity.
