Abstract: A breakthrough at the construction of traditional heat meter is made. A heat meter with transformable rotary-wings is developed by making some modification of a hot-water meter. The rotaryª²wings of the heat meter are made from metal sheet with two layers typed 5J11£¬and the precision of the heat meter is tested in hot-water. When the temperature of hot-water is between 40 degree and 80 degree,the error is less than ¡À5£¥£®Compared with other heat meters,heat meter with transformable rotary-wings is much more simple and chipper.
