Abstract
The calories' watch used for adopting the warm thermal energy to calculate, is the business units, such as residence, factory, school, store, hospital and the mineral mountain. to take water as the hot to provide the warm system into the door to calculate the appearance.
The calories' form according to enter the temperature of the water and water bad, and test to find out the discharge of the hot water to compute the calories. The temperature measures to adopt the platinum electric resistance temperature to spread the feeling machine, two form couples the temperature to spread the feeling machine to measure into the water temperature degree and a water temperature degrees respectively, getting the difference in temperature, the discharge measures to adopt a diagraph technique, using a wave to change the ability machine to produce a wave and accept a wave. Send out the frequency of a wave and shoot time from a machine control, flap the electric circuit and press to give or get an electric shock a creation machine vibration through, produce a wave, make use of the bad method, the discharge that beg the water.
This kind of calories measures the system adoption to imbed the system, having the ability of consume low, get in touch with not and can carry on the au to correct etc. to various parameters, such as temperature and pressure. function. Experiment the enunciation: This kind of calorimeter measures the accuracy to amount to 1.5 classes, and have the structure simple, the cost is low and the function strong etc. advantage.
