本文叙述弯管流量计的流量计算。对于实际使用的有一定粘性的流体(可压缩性忽略的情况下),将用弯管流量计测得的压差换算成流量的计算,必须考虑局部阻力损失的影响。本文在考虑局部阻力损失影响的基础上,提出了弯管流量计的流量计算公式。还以水为介质作例进行了计算。 This article describes the elbow flow meter flow calculation. For the actual use of a certain viscosity of the fluid (the case of negligible compressibility), the pressure drop measured by the elbow flow meter is converted to flow calculation, we must consider the impact of local resistance loss. Based on the consideration of the influence of local resistance loss, this paper proposed the formula of flow calculation of elbow flowmeter. Water is also used as an example for calculation.
