产品介绍：

Series FMS Flow Sensor FMS-1 is for applications requiring RELATIVE measurement and set-point of flow rate. This means that the actual velocity of the flow or the quantitative measurement in GPM is not known and is not important. What is important is that the set-point can be set as a "percentage of" or "relative to" the full flow rate. No other flow sensor could do it this simply or effectively. 

原理：
The model FMS uses a set of flashing LED's to indicate flow. All 7 of the LED's will remain lit to show ** flow rate. The flow OK light will also be lit showing that the established full flow rate is what is flowing in the pipe. When you initially set the flow rate, it will mark that as your ** mark. If your flow reduces below the 50% mark, you will get an alarm from the sensor. 

If flow increases beyond the initially established flow rate, the "Overflow" LED light will come on. It is then the operator's decisi
