PE孔板流量計提供整體式PVC結(jié)構(gòu),包括的支架或承載環(huán),其中包含計量龍頭和整體式墊片。與標準孔板不同,PE系列是真正的主要元件,包括用于壓差測量的各種部件。它設(shè)計用于任何有傳統(tǒng)流量孔板應(yīng)用的地方。為了提高效率和成本效益,它也可以代替其他初級差別生產(chǎn)者。PE系列有1/2英寸到24英寸的管線尺寸,用于空氣和大多數(shù)氣體。符合或超過ASME、AGA和ISO標準。
TE系列孔板流量計提供類似于OP和PE系列孔板的整體PTFE結(jié)構(gòu),該結(jié)構(gòu)包含一個的支架或承載環(huán),其中包含計量龍頭和整體式墊片。TE系列孔板適用于1/2“到24”的管線尺寸,可用于氣體、液體、腐蝕性和高溫流體。TE系列可以通過在標準法蘭(不需要孔板法蘭)之間滑動裝置來輕松安裝。TE系列設(shè)計用于任何有傳統(tǒng)流量孔板應(yīng)用的地方。為了提高效率和成本效益,它也可以代替其他初級差別生產(chǎn)者。
