LK-01 型流量控制器 LK-01 type of flow controller Lk-01型流量控制器是采用控制气体（或液体）流量大小并且能保持控制的流量稳重。适用下游（出口）压力不变而上游压力有变化中、小型试验装置的控制对象，它广泛应用在分析仪器上，（如：色普仪、红外分析仪、氧分析器等）用于稳重载气流或样品流的流量。 工业上以吹气法测量液位或比重时，用来稳定空气流量。 Lk-01型流量控制器具有结构合理适用维修方便，控制准确等特点，它是有控制器，针阀和转子流量计组成，适用时根据转子流量计的指示调节针阀的开度，即可获得所需之稳重流量。 Lk01 type flow controller is applied for controlling and stabilizing flow rate of gas （or liquid）it is widely used for smallmiddle test device of analytical instruments (such as chromatograp instrument,infrared analyzer ,oxygen analyzer and etc.)where downstream（outlet）pressure is constant while upstream varies。In industry，it is used for stabilizing air flow rate when measure liquid level and specific gravity by blowing way Lk-01 type flow controlling made of controller，valve，and rotameter owns characteitics，such as reasonable structure，convenient maintenance，accurate control and etc。to obtain requied stable flow rate，we just need to adjust the needle valve according to indicator on rotameter主要性能规范 Standards of main features工作压力 working pressure0.05-0.25MPa（10kgf/cm2）流量控制范围 Control range of flow rate20-1000ml/分（如不用转子流量计可达3000ml/分）20-1000ml/minute（can reach 3000ml/minute without rotameter）控制性能 Control performance输入压力变化 Tolerance of incoming pressure 10%输入流量变化小于 Tolerance of output flow less than 10%工作环境 Working atmosphere温度 Temperature range＋15%-50%相对温度relative humidity＜80%外型尺寸 Dimension 220 85 165全机重量 Total weight 2.4kg
