LWGYB型渦輪流量計

詳詢:0317-5562835

產(chǎn)品名稱:LWGYB型現(xiàn)場顯示渦輪流量計
產(chǎn)品分類:流量儀表-渦輪流量計
產(chǎn)品詳情
LWGY系列渦輪流量計基于力矩平衡原理,屬于速度式流量儀表。此流量計具有結(jié)構(gòu)簡單、輕巧、精度高、復(fù)現(xiàn)型號、反應(yīng)靈敏、安裝維護使用方便等有點,被廣泛用于石油、化工、冶金、供水、造紙等行業(yè),是流量計量和節(jié)能的理想儀表。

工作原理:
流體流經(jīng)傳感器殼體,由于葉輪的葉片與流向有一定的角度,流體的沖力使葉片具有轉(zhuǎn)動力矩,克服摩擦力矩和流體阻力之后葉片旋轉(zhuǎn),在力矩平衡后轉(zhuǎn)速穩(wěn)定,在一定的條件下,轉(zhuǎn)速與流速成正比,由于葉片有導(dǎo)磁性,它處于信號檢測器(由永久磁鋼和線圈組成)的磁場中,旋轉(zhuǎn)的葉片切割磁力線,周期性的改變著線圈的磁通量,從而使線圈兩端感應(yīng)出電脈沖信號,此信號經(jīng)過放大器的放大整形,形成有一定幅度的連續(xù)的矩形脈沖波,可遠傳至顯示儀表,顯示出流體的瞬時流量或總量。

優(yōu)點:
精度高:液體0.15%~0.5%,氣體1%~1.5%;
重復(fù)性好:0.05%~0.2%;
量程比寬:10~50:1;
脈沖信號輸出,抗干擾能力強;
耐壓高、壓力損失小、反應(yīng)速度快;
有可動部件,易磨損;
對介質(zhì)有一定的清潔度要求;
需要前后直管段分別為10D和5D。

LWGYB型現(xiàn)場顯示渦輪流量計是在LWGY基本型渦輪流量傳感器的基礎(chǔ)上,采用電池供電,增加了現(xiàn)場顯示功能。該流量計采用先進的超低功耗單片微機技術(shù)研制的傳感器與顯示積算一體化的新型流量測量儀表。與傳統(tǒng)的渦輪流量傳感器配二次儀表組成的測量系統(tǒng)相比,它具有體積小、重量輕、顯示讀數(shù)只管、清晰、可靠性高、不受外界電源影響、抗雷擊、成套成本低等明顯優(yōu)點??蓮V泛應(yīng)用于石油、化工、輕工、食品等行業(yè)的液體流量測量。
