渦街流量計(jì)常見(jiàn)故障：一臺(tái)DN50渦街流量計(jì)，從說(shuō)明書(shū)查到，其液體用流量范圍是3-50m3/h。我們?cè)谟土鳂?biāo)準(zhǔn)裝置上標(biāo)定的結(jié)果是10-50 m3/h符合精度要求，但10m3/h以下精度不合格，應(yīng)如何評(píng)價(jià)此臺(tái)流量計(jì)？ </p> <p> 渦街流量汁說(shuō)明書(shū)中，標(biāo)明的流量范圍是使用于特定參考介質(zhì)的流量范圍，如液體—般指常溫水。用于其他介質(zhì)時(shí)，可用流量范圍將隨介質(zhì)的粘度和密度不同而異。由于油流量標(biāo)準(zhǔn)裝置采用粘度比水大，密度比水小的柴油做標(biāo)定介質(zhì)，流量計(jì)的下限流量—般都會(huì)相應(yīng)提高，使可用流量范圍變窄，廣元渦街流量計(jì)。所以，渦街流量計(jì)在油流量標(biāo)定裝置上標(biāo)定出現(xiàn)小流量性能變差是正常的，廣元渦街流量計(jì)，廣元渦街流量計(jì)。由此我們不難推斷，如果用液化石油氣(這種低粘度介質(zhì))標(biāo)定渦街流量汁，將會(huì)得到比水好的相反結(jié)果。
