Abstract:
Based on the fundamental principle of the measurement of the heat quality and the technology index of heating system , a design scheme of the non-contact calorimeter for heating system is introduced based on ultrasonic measurement technology, and the design structures of the hardware and software are given ,This calorimeter is no-contact, accurate, and has functions of low power consumption, auto-compensation for temperature and pressure. The experiment shows that its accuracy class is 2 ,and its structure is simple, its price is lower, and its practicability has been validated.
Key words: ultrasonic; Doppler effect; calorimeter; non-contact measurement; single chip processor
