下图表示的是Ketema Mc Crometer的V-锥体流量计测量装置的示意图。据介绍,它具有准确度高、重复性好、受安装环境条件的影响小、磨损小、量程变化范围宽等优点和自整流的能力。适用于水、汽、空气、蒸气、天然气、氮气和乙醇;流动状态从低温流动直到超临界流动;使用的环境温度可达370℃,压力可达42kg/cm~2(1kg/cm~2=98×10~4Pa);流体流的雷诺数可达5兆;满量程差压信号从低于250mm水柱到数米水柱(1mmH_2O=9.8Pa)。
The figure below shows a schematic of a Ketema Mc Crometer V-cone flowmeter. According to reports, it has the advantages of high accuracy, good repeatability, small influence by the installation of environmental conditions, small wear and tear, a wide range of range changes and the ability of self-rectification. Suitable for water, steam, air, steam, natural gas, nitrogen and ethanol; flow from low temperature to supercritical flow; ambient temperature up to 370 ℃, pressure up to 42kg / cm ~ 2 98 × 10 ~ 4Pa); Reynolds number of the fluid flow can reach 5 trillion; full range differential pressure signal from less than 250mm water column to several meters water column (1mmH_2O = 9.8Pa).
