Heat Meter Ultrasonic Flowmeter

Heat metering refers to the measurement and charging of heat based on heat metering instruments, with central heating or regional heating as the premise, through certain charging policies or heat distribution methods. In layman’s terms, it means paying heating fees based on the heat value measured by the heat metering instrument.
