The Design of Vortex Flowmeter

This paper analysis the working mechanism and structure of vortex flowmeter and the street flow meter hardware circuit design. Signal conditioning circuit was designed including ultrasound transmitter receiver processing circuit, traffic signal conditioning circuit ,programmable amplifier and anti aliasing filter circuit.The temperature measuring circuit , infrared communication circuit and supersonic signal control electric circuit. These circuit to ultrasound dedicated chips UTA6902 as core. The vortex flowmeter was design of the design of liquid crystal display program, the design of temperature programming and the design of ultrasonic signal acquisition and processing program. It can be verified in the experiment.
