| Abstract: | Lowpower vortex flowmeter is applied to battery power with a temperature compensationof single - phase fluid measurement. It is a low power consumption and standard industrial instrument which is suitable for the pulse or frequency of the two - wire sensor output, measurement and display of the second flowrate. The flowrate meter is designed by using TI＇ sultra - low power MSP430F449 MCU. It has a battery charger, liquid crystal display, multi -output mode and power- down data protection storage features. |
