| Abstract | Abstract:- Based on the characteristics of ultrasonic non-contact measurement and the combination of temperature measurement with ultrasonic flow measurement, a flowmeter was designed. The structure of the ultrasonic flowmeter and the circuits of temperature and flow measurement were described. The design method of the meter with low power consumption was given by selecting MSP430 single chip microcomputer. In order to enhance flowmeter's precision and stability a Xilinx CoolRunner CPLD was applied in high precision timing. The result is a low cost portable solution working with a 3.3V supply and operating with ultrasonic transducers at 1MHz frequency. Key-Words:- ultrasonic flowmeter, delay line, transit-time, CPLD, ultrasonic transducer 1 |
