一种耐高温的涡街流量计
本技术涉及涡街流量计
,特别涉及一种耐高温的涡街流量计。
技术介绍
涡街流量计也称为旋涡流量计或卡门涡街流量计,涡街流量计是依据卡门旋涡原理进行封闭管道流体流量测量的新型流量计。因其具有良好的介质适应能力,无需温度压力补偿即可直接测量蒸汽、空气、气体、水、液体的工况体积流量,配备温度、压力传感器可测量标况体积流量和质量流量,是节流式流量计的理想替代产品现有的涡街流量计在使用的过程中,压电芯片只能测量400摄氏度内的流体,当压电材料的温度达到更高值后,压电效应会减少甚至自行消失,这时流量计就无法得到漩涡频率信号,使得涡街流量计的工作温度范围受到了限制。目前也出现了一些涡街流量计耐高温改进装置,但是主要是通过在法兰连接座外侧设置散热片进行散热,散热效率较低。
技术实现思路
本技术的目的在于一定程度上解决上述问题,提供了一种耐高温的涡街流量计,利用散热片结合流体进行散热,散热效果好,能够大幅度的提高涡街流量计的测量温度。本技术方案提出一种耐高温的涡街流量计,包括涡街流体管道、设置在涡街流体管道内部的涡街发生体、设置在涡街流体管道上端与涡街流体管道一 ...
