The Research of Flow Meter Dynamic Simulation Test

Abstract:

The flow signal is one of the main parameters of hydraulic system monitoring. Since the majority of fault features can be shown by dynamic traffic signal, The study of dynamic traffic signal has very important significance on the evaluation of the performance of hydraulic element and characteristics of the hydraulic system. In this paper, the flow meter dynamic signal was simulated by the self-designed test-bed called multi-functional gear flow meter speed detection test-bed. The experiment indicates that the using PLC control of inverter and motor can realize high frequency dynamic oscillating of gear, oscillation frequency can reach 2Hz above. If the accuracy is met with, flow meter dynamic characteristic can reach 10Hz through the test-bed simulation, which provides the basis of theory and experiment for the real-time dynamic flow characteristics test.
