The supply form can bedivided into components and complete sets of devices.

        L系列标准孔板流量计是测量流量的差压感受元件。配合差压变送器以及显示、记录、积算和调节仪表，可用来测量计算液体，蒸汽和气体的瞬时流量值和累计流量值。由于结构简单制造方便，安装容易，使用时间长，价格便宜等特点，在流量仪器中是应用最广泛，最成熟的一种。在国外和国内有着其固有的巨大市场，用户熟悉、数据完善；遵循国际标准计算与加工、使用灵活方便；国内目前流量测量中应用最广泛的仍然是差压式流量计，据有关资料的估计占流量仪表总用量的75%-85%之间。它在蒸汽锅炉、石油、化工、钢铁、电力、水利、造纸、制药、食品和化纤等行业中被广泛使用。

        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.
