L系列標(biāo)準(zhǔn)孔板流量計(jì)是測(cè)量流量的差壓感受元件。配合差壓變送器以及顯示、記錄、積算和調(diào)節(jié)儀表,可用來測(cè)量計(jì)算液體,蒸汽和氣體的瞬時(shí)流量值和累計(jì)流量值。由于結(jié)構(gòu)簡(jiǎn)單制造方便,安裝容易,使用時(shí)間長(zhǎng),價(jià)格便宜等特點(diǎn),在流量?jī)x器中是應(yīng)用泛,的一種。在國(guó)外和國(guó)內(nèi)有著其固有的巨大市場(chǎng),用戶熟悉、數(shù)據(jù)*;遵循國(guó)際標(biāo)準(zhǔn)計(jì)算與加工、使用靈活方便;國(guó)內(nèi)目前流量測(cè)量中應(yīng)用泛的仍然是差壓式流量計(jì),據(jù)有關(guān)資料的估計(jì)占流量?jī)x表總用量的75%-85%之間。它在蒸汽鍋爐、石油、化工、鋼鐵、電力、水利、造紙、制藥、食品和化纖等行業(yè)中被廣泛使用。
L-series standard orifice flowmeter is adifferential pressure sensing element used to measure flow. Combined withdifferential pressure transmitters and display, recording, accumulation, andadjustment instruments, it can be used to measure and calculate the instantaneousflow rate and cumulative flow rate values of liquids, vapors, and gases. Due toits simple structure, convenient manufacturing, easy installation, long usagetime, and low price, it is the most widely used and mature type in flowinstruments. It has an inherent huge market both abroad and domestically, withfamiliar users and complete data; Following international standards forcalculation and processing, flexible and convenient use; At present, the mostwidely used flow meter in China is still the differential pressure flowmeter,which is estimated to account for 75% -85% of the total usage of flowinstruments according to relevant data. It is widely used in industries such assteam boilers, petroleum, chemicals, steel, electricity, water conservancy, papermaking,pharmaceuticals, food, and chemical fibers.
