　　The regulation of voltage stabilization compensation for vortex flowmeter is introduced by Xi'an Huaheng Instrument:Why need voltage stabilization compensation for measuring high temperature gas by vortex flowmeter?Because the influence of volume temperature and pressure of gas is relatively large,there will be pressure inside the pipeline when measuring high temperature gas.The volume of gas will expand because of temperature,but the volume of gas will be increased because of pressure.Compression,therefore,in the absence of compensation,the flow rate measured by the vortex flowmeter is quite different from the actual flow rate.

 

　　按照測(cè)量原理來(lái)說(shuō)，我們的流量計(jì)實(shí)際上只能測(cè)量當(dāng)前工況下流體流過(guò)的體積，所以這個(gè)情況對(duì)我們不實(shí)用。

 

　　According to the principle of measurement,our flowmeter can only measure the volume of fluid flowing through the current working condition,so this situation is not practical for us.

 

　　我們實(shí)際上使用的時(shí)候，是想測(cè)量流過(guò)多少質(zhì)量的流體。而蒸汽在不同的壓力和溫度下，密度變化很大，所以就要在測(cè)量蒸汽流過(guò)多少體積的同時(shí)要測(cè)量壓力和溫度。只有時(shí)刻了解蒸汽的密度才可以，準(zhǔn)確測(cè)量出蒸汽的質(zhì)量。

 

　　When we actually use it,we want to measure how much mass of fluid is flowing.The density of steam varies greatly under different pressures and temperatures,so it is necessary to measure both pressure and temperature while measuring the volume of steam flow.Only when the density of steam is known at all times can the quality of steam be measured accurately.

 

　　所謂補(bǔ)償，就是根據(jù)流體的溫度和壓力數(shù)據(jù)來(lái)計(jì)算出流體的密度，從而根據(jù)測(cè)量出來(lái)的流體體積，計(jì)算出流體質(zhì)量。

 

　　The so-called compensation is to calculate the density of the fluid according to the temperature and pressure data of the fluid,so as to calculate the mass of the fluid according to the measured volume of the fluid.

 

　　至于水蒸汽的補(bǔ)償，如果水蒸汽是飽和蒸汽就要進(jìn)行壓力或者溫度補(bǔ)償（溫度補(bǔ)償和壓力補(bǔ)償各選其一）。如果是過(guò)熱蒸汽則要進(jìn)行溫壓補(bǔ)償（溫度補(bǔ)償和壓力補(bǔ)償同時(shí)進(jìn)行）。

 

　　As for the compensation of water vapor,if the water vapor is saturated vapor,pressure or temperature compensation(temperature compensation and pressure compensation each choose one).If it is superheated steam,temperature and pressure compensation(temperature compensation and pressure compensation at the same time).

 

　　注意一點(diǎn)，在水蒸汽的分類中，飽和蒸汽和過(guò)熱蒸汽，千萬(wàn)不能弄錯(cuò)，因?yàn)轱柡驼羝拿芏仁歉哂谶^(guò)熱蒸汽的，在儀表的選擇和設(shè)置時(shí)一定要注意。一旦在這個(gè)地方搞錯(cuò)，會(huì)造成嚴(yán)重的經(jīng)濟(jì)損失。

 

　　Note that in the classification of water vapor,saturated vapor and superheated vapor must not be mistaken,because the density of saturated vapor is higher than that of superheated vapor,and attention must be paid to the selection and installation of instruments.Once you make a mistake in this place,it will cause serious economic losses.

 

　　當(dāng)然也有一些儀表，不必區(qū)分水蒸汽是飽和蒸汽還是過(guò)熱蒸汽，因?yàn)樗鼈兂私訙y(cè)量流量的裝置外，同時(shí)也接有測(cè)量溫度和壓力的裝置。

 

　　Of course,there are also some instruments,which do not need to distinguish between saturated steam and superheated steam,because they are connected not only with flow measurement devices,but also with temperature and pressure measurement devices.
