摘要
本文依据文丘里流量计的原理,提出了一种新型量水计,利用孔口隔片取代文丘里流量计喉道以后的部分,并用压力表代替测压管,同时把压力表的刻度数值换算成流量值,测流时直接读取流量值,结构简单,计量精度高,特别适合农村机井和机电灌站灌溉管道的流量计量。
This paper developed a new flow meter according to the Venturi meter principle. The throat part of the Venturi meter is substituted by an opening plate and the piezometer is changed by a pressure meter with a directly flow reading. The flow can be directly read in flow measurement without any conversion. This new flow meter has the advantages of simple structure, high precision and is specially suitable for the irrigation pipe line flow measurement in the rural pumping well and pumping station.
