蒸汽流量表產(chǎn)品介紹
蒸汽流量表是利用液體振動原理而開發(fā)的一種新型流量計,廣泛應(yīng)用在石油、化工、冶金、造紙等行業(yè)流體的計量。該流量計無可動部件,可靠性強(qiáng)、精度高、壽命長,可在很寬的流量范圍內(nèi)精確測量液體的瞬時流量和累計流量。其不受介質(zhì)溫度、壓力、粘度及組分的影響,同時不堵、不卡、不易結(jié)垢、耐高溫、高壓,安全防爆,適用于惡劣環(huán)境。流量計分一體化顯示和遠(yuǎn)傳顯示,并可輸出脈沖信號或電流信號與微機(jī)聯(lián)網(wǎng)。
蒸汽流量表可以替換在現(xiàn)場無法正常工作的分流旋翼式蒸汽流量計,現(xiàn)場液晶表頭顯示瞬時流量、累積流量,切換顯示實時溫度、實時壓力、有溫度、壓力補(bǔ)償功能,在測量氣體、蒸汽時,根據(jù)實測溫度、壓力進(jìn)行查表方式補(bǔ)償,保證流量不受溫度、壓力變化,引起汽體密度的變化而影響流量計準(zhǔn)確性。在飽和蒸汽和過熱蒸汽轉(zhuǎn)換狀態(tài)下可自動切換。zui大工作壓力:4Mpa ;zui大工作溫度450℃。使用這種流量計可以大大提高計量的準(zhǔn)確度。
?
蒸汽流量表流量儀表測量的是介質(zhì)的工作狀態(tài)體積流量,因此應(yīng)先根據(jù)工藝參數(shù)求出介質(zhì)的工作狀態(tài)體積流量 , 相關(guān)公式如下:
( 1 )已知?dú)怏w標(biāo)準(zhǔn)狀態(tài)體積流量,可通過以下公
式求出工況體積流量
公式( 3 )
(2) 已知?dú)怏w標(biāo)準(zhǔn)狀態(tài)密度ρ,可通過以下公
式求出工況密度
公式( 4 )
( 3 )已知質(zhì)量流量 Q m 換算為體積流量 Q v
公式( 5 )
式中:
Q v : 介質(zhì)在工況狀態(tài)下的體積流量 (m 3 /h)
( Q v = 3600f /K K: 儀表系數(shù) )
Q o : 介質(zhì)在標(biāo)準(zhǔn)狀態(tài)下的體積流量 (Nm 3 /h)
Q m : 質(zhì)量流量 (t/h)
ρ: 介質(zhì)在工況狀態(tài)下的密度 (kg/m 3 )
ρ o :介質(zhì)在標(biāo)準(zhǔn)狀態(tài)下的密度 (kg/m 3 ) ,常用氣體介質(zhì)的標(biāo)準(zhǔn)狀態(tài)密度,見表(三)
P : 工況狀態(tài)表壓 (MPa)
t : 工況狀態(tài)溫度 (℃)

蒸汽流量表流量范圍
該儀表具有量程寬、精度高、壓力損失小、介質(zhì)通用性好、有與流量成比例的脈沖信號輸出、便于個計算機(jī)聯(lián)用等優(yōu)點(diǎn)。由于傳感器采用的檢測探頭與旋渦發(fā)生體分開安裝而且耐高溫的壓電晶片不與介質(zhì)接觸,所以儀表具有結(jié)構(gòu)簡單、通用性好和穩(wěn)定性。
