CEL-52型膜盒差压流量计是与孔板等节流装置配套、能作压力波动影响补偿的流量仪表,专门用以测量饱和蒸汽流量。本仪表针对工业锅炉饱和蒸汽流量测量中工况常有变动的特定条件,用较简单的组件补偿压力波动影响,从而在蒸汽负荷波动、压力变化幅度较大的情况下,获得一定的测量精确度。相对说来,这是一种“价廉”的仪表,价格约为DDZ-Ⅱ型仪表的 1/3。
CEL-52-type diaphragm differential pressure flow meter and orifice plate and other throttling devices, can make pressure fluctuations affect the flow of compensation instruments, designed to measure the saturated steam flow. The instrument for industrial boiler saturated steam flow measurement conditions often change the specific conditions, with a simple component to compensate for the impact of pressure fluctuations, thus the steam load fluctuations, large pressure changes in the circumstances, access to a certain degree of measurement accuracy . Relatively speaking, this is a “cheap” instrument, the price is about DDZ-Ⅱ type instrument 1/3.
