The invention aims to provide a passive heat metering device and a heat metering system working by the passive heat metering devices. The heat metering device comprises a temperature difference power supply system, a reflection type ultrasonic flowmeter, a temperature sensor, a communication interface, a ZigBee controller and a liquid crystal display (LCD). By using characteristics of a concentrative heating and cooling system, the passive heat metering device automatically supply power through the temperature difference power supply system; a power supply is not required to be regularly replaced, so that the passive heat metering device is energy-saving and environment-friendly; the heat metering system works by two same passive heat metering devices provided by the invention; the two devices run in a low-power mode; the working modes of a main node and a slave node are regularly changed; under the conditions of heating and cooling, the system selects different metering programs to match different power supply capacities of a power supply system; and the passive heat metering device can be simultaneously suitable for heat metering of the heating and cooling system.
