一、流量开关工作原理
缺点： ➢ 响应慢； ➢ 受污垢和铁锈影响较大，必须定期清洗； ➢ 对于粘性液体在使用上受到限制。
二、流量开关清洗方法
流量开关清洗方法
（1）断开流量开关电源； （2）确认管路无压，拆卸流量开关； （3）用清洗液清洗流量开关测量部件，防止腐蚀流量开关外壳或清洗人皮肤； （4）清洗完毕，用清水冲干净； （5）回装，密封紧固。
➢ 当管道内没有介质流动时，感热传感器探测到的热量是一个恒定值；当 有介质流动时，流体经过探头的时候，会带走加热线圈的一部分热量， 感热传感器所接收到的热量将随介质的流速变化而变化，感热传感器将 这温差信号转化成电信号，在流速达到某设定点时，流量开关输出开关 量信号。

3、控制器靶与介质流动方向垂直；
4、控制器前需要10倍管道直径长度的导向直通道；
5、打开控制器罩壳，按接线图接线，然后装好罩壳。
LKB靶式流量控制器采用靶式传感器，可用于水，冷却系统或其它流体回路，控制器的设定值可调。

One set of diaphragms monitors the pressure differential and operates themicro switch through the rod @ and operating lever ;.The rod @ moves downward with increased flow, and upward with decreased flow.Moving the gear = upward or downward by the adjusting gear . manually offersan electric signal at various flow rates.Adjusting gearGearFlow settingindication leverBodyRodOperating leverMicro switchProtection diaphragm1083Series IFW5Flow SwitchDiaphragm Style Flow SwitchPFMPFMVIFW5:0-::-10 to 24(With terminal box)DimensionsIFW5:0-::-00 to 04(Without terminal box)With neon lightLead wire length 500With neon lightSeries IFW510841085Series IFW5Flow SwitchDiaphragm Style Flow SwitchDimensionsIFW5:0-::-55 to 86(With light, Terminal box for 24 VDC)PFM PFMVB (NC)A (NO)C (COM)B (NC)A (NO)C (COM)AdjustingBe sure to read before handling.Refer to front matter 56 for Safety Instructions and pages 952 and 953 for Flow Switch Precautions.Caution1.Mount a switch, so that the liquid flow is in the same direction as that of the arrow on the body.2.Be sure to fill the passage with the fluid.3.The flow switch can be installed either horizontally or vertically.4.Provide a straight pipe portion that corresponds to approximate-ly 5 times the bore of the pipe before and after the area of the pipe on which the product is installed, thus keeping the product as far away as possible from the elements that disturb the flow, such as elbows or valves.5.For wiring, refer to the internal wiring diagram.6.If a terminal box is not available, wire by selecting the contact at 1a or 1b. At that time, insulate the lead wires that will not be used.7.Because this is an open style, it cannot be used where water or oil splashes.8.It cannot be used if a water hammer or pulsation pressure is ap-plied to the fluid.9.In order to prevent a malfunction or diaphragm damage caused by debris or cutting chips in the fluid, install a filter with approxi-mately 100 mesh on the inlet side of a flow switch.1. To adjust flow, remove grommet of the upper cover and rotate flow adjusting gear using a flat head screwdriver.Turning clockwise can increase the set flow and turning coun-terclock can decrease the set flow.2. The flow rate setting point is set at the ON flow rate. Therefore, in the case of the 1a contact, the ON signal is output if fluid with a higher flow rate than the set flow rate has occurred.In the case of the 1b contact, the ON signal is output when the flow rate has decreased from the set flow rate for the amount that corresponds to the hysteresis.3. To prevent the chattering that is associated with the fluctuation of the operating flow rate, set the difference between the set flow rate and the operating flow rate so that it is as large as pos-sible.4. Use at or below the maximum operating pressure and maximum flow rate.5. The indicator on the window name plate (Fig. 1) is only a guide-line. For precise setting, mount a flow meter on the downstream side of the flow switch, and set the level.Also, when setting levels with a low flow rate at pressures of 0.2 MPa or more, there may be interference between the indicator needle and the scale plate. In such cases, detach the indicator needle and scale plate before setting. After setting, the indicator needle and scale plate can be reattached in positions of your choice.Graduations for IN pressure 0.1 MPa Graduations foradjusting on flow rateGraduations for IN pressure 0.2 MPaFig. 1 Window name plateIFW5:0-::-00/10/20IFW5:0-::-01 to 04/11 to 14/21 to 24IFW5:0-::-55/56IFW5:0-::-65/66IFW5:0-::-75/76IFW5:0-::-85/86Internal Wiring Diagram1086Series IFW5。
