    • PURPOSE: A flow meter for a valve remote control system is provided to remove accumulated errors generated from an oil pressure generator and a temperature change in the inside of a hydraulic line, thereby automatically performing a zero point adjustment. CONSTITUTION: A flow meter(10) for a valve remote control system comprises a rotor(100), a sensor(120), and a signal processor(130). The rotor is formed in the inside of a fluid pipe(200) connecting an oil pressure generator(20) and a valve actuator(300), thereby being rotated by a flow of a fluid. The sensor senses rotation and a direction of the rotor, thereby transmitting the same with electric signals. The signal processor receives the signals of the sensor, thereby analyzing a flow rate and a forward-and-backward direction of the fluid. The signal processor outputs opening/closing information of the valve actuator. When underactuation within a preset error range is sensed during a predetermined time period after opening/closing the valve actuator, the sensed underactuation is regarded as noises caused by output errors of the oil pressure generator so that the signal processor forcibly performs a zero point adjustment to make the valve actuator be in a normal state.
    • 目的:提供一种用于阀门遥控系统的流量计,以消除油压发生器产生的累积误差和液压管路内部的温度变化,从而自动进行零点调整。 构成:用于阀门遥控系统的流量计(10)包括转子(100),传感器(120)和信号处理器(130)。 转子形成在连接油压发生器(20)和阀致动器(300)的流体管道(200)的内部,从而通过流体流动而旋转。 传感器感测旋转和转子的方向,从而用电信号传输它。 信号处理器接收传感器的信号,从而分析流体的流速和前后方向。 信号处理器输出阀致动器的打开/关闭信息。 在打开/关闭阀致动器之后的预定时间段期间感测到在预设误差范围内的不足动作时,感测到的欠驱动被认为是由油压发生器的输出误差引起的噪声,使得信号处理器强制执行零点调整 使阀门执行器处于正常状态。
