摘　　要：目前对苯二甲酸(PTA)投产规模及产能越来越大,对应管道的尺寸也在放大,如果选用大尺寸的流量计,势必增加成本;且PTA装置属于连续运行装置,大口径的流量计在检修维护方面也存在难度。通过使用并联流量计可以有效降低后期的检修维护费用,且能保证装置的安全稳定运行。Currently PTA production scale and production capacity are getting larger and larger,and the size of corresponding pipelines is also expanding.If large-diameter flowmeter is selected,it will increase the cost.PTA devices belong to continuous operation devices,and large-diameter flowmeters also have difficulties in overhaul and maintenance.The later maintenance costs can be effectively reduced through the use of parallel flowmeter,and can ensure the safe and stable operation of the device.
