模拟流量 meaning in English

analogue flow rate

And then , a method of load - flow low - pressure measurement was proposed in the light of the hydraulic - resistance theory of servo valve . the validity of the method was proved by the experimental results . therefore , the measurement of the characteristic of load - flow and no - load flow can be realized by using this method
然后根据电液伺服阀的液桥理论提出了一种负载流量低压测量方法，在所开发的测试系统上，利用电液比例阀模拟流量测量装置对所提出的方法进行了试验验证，实现了利用低压流量计和压力传感器进行电液伺服阀负载流量特性和空载流量特性的测量。
