插入式超声波流量计在供水大口径管道中的应用

Application of Bayonet Ultrasonic Flow Meter in Supplying Water Heavy-calibre Pipeline

在供水系统计量中,工业流量测量普遍存在着大管径、大流量测量困难的问题,机械式水表使用较多,大管径流量的水表存在误差较大,计量不准,无校验手段。本文探讨在供水大口径管道中应用超声波流量计,并对该性能进行分析对比,提高供水计量的准确性。分别选用MF-G2和TDS-100型插入式超声波流量计,在现场应用,效果较好,精确度达到1%。

In the water-supply system measurement, the problem is that it is difficult to measure the great pipe diameter or large flow. There are more applications of the machinery type water gauge. The large pipe diameter flow water gauge has the problem of big error, inaccurate measurement, no check-up means. The paper probes the application of the ultrasonic flow meter in supplying water heavy-calibre pipeline, and analyses the contrast of the performance, improves the accuracy of supplying water measurement. The selection of MF-G2 and TDS-100 bayonet ultrasonic flow meter for use separately in scene application, the result is better, and the accuracy reach 1%.
