The prepaid IC card steam flowmeter system consists of a steam flow sensor, pressure sensor, temperature sensor, IC card prepaid controller, IC card, card reader, and recharge software. There is a common management mindset of "heavy equipment, light measurement" in current heating enterprises. The measuring facilities used are outdated, small flow meters do not output, large flow meters do not move, and the measuring instruments installed on site do not have reliable anti-theft measures... The existence of such phenomena invisibly increases the pipe damage of heating enterprises and easily leads to measurement disputes and difficulties in charging. Once a heating enterprise incurs arrears, it is likely to use various social relationships to evade and delay payment, but it is difficult for heating enterprises to stop gas due to arrears, and the arrears often become more and more outstanding, which is difficult to solve. In the long run, this stubborn problem will spread to other heating enterprises. In addition, the dishonesty of individual heating enterprises and the problems caused by business operations will also spread to other heating enterprises. Shutdown and merger have caused unbearable suffering for heating enterprises. Therefore, in order to ensure the normal operation and legitimate rights and interests of heating enterprises, and to eliminate such positive phenomena, we have developed a "steam metering prepayment device" using mature technological means, with the concept of "paying first, then using steam"

Management process after installing the "Steam Measurement Prepaid Device"

After installing the "Steam Metering Prepaid Device" at the user's site, the user * * pays the steam fee in advance to the heating unit. After the steam fee is confirmed by the finance department of the heating enterprise, relevant personnel are notified to use the recharge software to recharge the user's IC card. The heating network management personnel bring the IC card to the site for "card swiping". After receiving the information from the IC card, the device will calculate the user's available steam volume based on the set steam unit price, and automatically start the valve for steam supply, dynamically displaying the remaining available steam volume, remaining amount, and all measurement parameters.

When the remaining amount of the user is insufficient, the on-site instrument will emit a buzzing alarm sound to remind the customer to pay as soon as possible (in conjunction with the remote monitoring system of the heating network, mobile SMS notification can be achieved). Otherwise, when the balance in the meter reaches zero, the system will automatically close the valve and stop heating.

At the same time, to avoid human modification of the measuring instruments installed on site, our company will provide anti-theft boxes to uniformly cover the relevant instruments and lock them using wireless remote control. They can only be opened normally after unlocking with the remote control. Otherwise, it will be considered as car theft and the system will automatically close the valve and stop the steam.
