摘　　要：为解决超声波流量计无预付费功能,且单声道超声波流量计计量可靠性低。本文研究了一款CPU卡预付费多声道超声波流量计,集气体超声波流量计基表、CPU卡流量补偿控制仪、卡控阀门于一体,具有流量计量和控制的功能。该款CPU卡预付费多声道超声波流量计结构紧凑,能够对涡流和不对称流进行检测,可靠性高。In order to solve the problem that the ultrasonic flowmeter has no prepayment function,and the measurement of the monophonic ultrasonic flowmeter has low reliability.This article studies a CPU card prepaid multi-channel ultrasonic flowmeter,which integrates a gas ultrasonic flowmeter meter,CPU card flow compensation controller,and valve.It has the functions of flow measurement and control.The CPU card prepaid multi-channel ultrasonic flowmeter has a compact structure,can detect eddy currents and asymmetric flows,and has high reliability.
