摘要
多年来，叶轮式流量计在许多领域得到了较多的实际应用，其工作原理比较简单，概括的讲就是应用流体动量矩原理测量流量的装置。叶轮的旋转角速度与流量成线形关系，测得旋转角速度就可测得流量值。目前叶轮式流量计的研究重点仍然集中在流量的采集与流量曲线参数校正上，不论采用无磁还是有磁传感器，对其流量曲线的校正都是相当麻烦和困难的，功耗与可靠性均达不到理想的效果，制造难度和成本也较高。应用LC9723-IC芯片解决上述问题是目前较好的方法。
Impeller-type flowmeter in the years of practical application, its working principle is relatively simple, general talk about is the principle of angular momentum of fluid flow measuring device. Impeller rotation angular velocity and flow into a linear relationship, the measured angular velocity of rotation can be measured flow value. Current research focuses on impeller flowmeter is still concentrated in the collection and flow of traffic on the calibration curve parameters, regardless of use of non-magnetic, or have magnetic sensors, its flow curve correction ~bles are very cumbersome and difficult, power and reliability each contributed less than ideal results, manufacturing difficulty and cost has also increased. Applications LC9723-IC-chip address the above problems is the best way.
