<BR>HLV威力巴流量计采用了完全符合空气动力学原理的工程结构设计，是一种在精度、功效及可靠方面达到了无比卓越程度的传感元件。 <BR>二、威力巴流量计主要技术指标 <BR>1、威力巴流量测量系统性能指标 <BR>测量精度：± 1 重复精度：± 0.1 <BR>适用压力：0～40MPa 适用温度：－ 180℃～＋ 550℃ <BR>测量上限：取决于探头强度测量下限：取决于测量最小差压要求 <BR>量 程 比：大于10∶1 <BR>适用管径：38mm～9,000mm 圆管、方管 <BR>适用介质：满管、单向流动的、单向的气体、蒸汽和粘度不大于1 0 厘泊的液体 <BR>威力巴的使用范围及其广泛，它大量用于各种气体、液体和蒸 <BR>汽的测量，以下为典型应用介质。 <BR>气体/液体/蒸汽 <BR>天然气/冷却水/饱和蒸汽 <BR>压缩空气/锅炉水/过热蒸汽 <BR>燃气/除盐水 <BR>气体碳氢化合物/液体碳氢化合物 <BR>热空气/低温液体 <BR>发生炉气体/导热液体 <BR><BR>三、HLV管道式威力巴流量计工作原理简介 <BR>当流体流过探头时，在其前部产生一个高压分布区，高压分布区的压力略高于管道的静压。根据伯努利方程原理，流体流过探头时速度加快，在探头后部产生一个低压分布区，低压分布区的压力略低于管道的静压。流体从探头流过后在探头后部产生部分真空，并在探头的两侧出现旋涡。均速流量探头的截面形状、表面粗糙状况和低压取压孔的位置是决定探头性能的关键因素。低压信号的稳定和准确对均速探头的精度和性能起决定性作用。威力巴均速流量探头能精确地检测到由流体的平均速度所产生的平均差压。威力巴均速流量探头在高、低压区有按一定准则排布的多对取压孔，使准确测平均流速成为可能. <BR><BR>四、威力巴流量计测量原理 <BR>HLV威力巴流量计是一种插入式流量测量仪表。在管道中插入一根威力巴传感器 , 当流体流过传感器 时 , 在其前部 迎流方向 产生一个高压分布区 , 在其后部产生一个低压分布区。传感器在高、低压区有按一定规则排列的多对 一般为三对 取压孔 , 分别测量流体的全压力 包括静压力和平均速度压力 Pl和静压力 P2。将 P1 和 P2 分别引入差压变送器 , 测量出差压 △P=P1-P2, △P反映流体平均速度的大小 , 以此可推算出流体的流量。 <BR><BR>技术参数及应用<BR><BR> <TABLE style="WIDTH: 98%; BORDER-COLLAPSE: collapse" border=1 cellSpacing=0 cellPadding=0 width="98%" align=center> <TBODY> <TR>
