DWYER FMS系列流量開關產品信息

DWYER FMS系列流量開關詳細信息：
產品名稱: FMS系列流量開關
產品型號: FMS系列

適用于水或油，輸出：PNP常開或PNP常閉

產品介紹：

Series FMS Flow Sensor FMS-1 is for applications requiring RELATIVEmeasurement and set-point of flow rate. This means that the actualvelocity of the flow or the quantitative measurement in GPM is notknown and is not important. What is important is that the set-pointcan be set as a "percentage of" or "relative to" the full flowrate. No other flow sensor could do it this simply oreffectively.

原理：
The model FMS uses a set of flashing LED's to indicate flow. All 7of the LED's will remain lit to show * flow rate. The flow OKlight will also be lit showing that the established full flow rateis what is flowing in the pipe. When you initially set the flowrate, it will mark that as your * mark. If your flow reducesbelow 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'sdecisions as to whether to ignore it if too much flow is not aproblem and may actually choose this flow rate to be the new"normal" flow rate. This can be done by just depressing the "set"button until all LED's flash. The FMS has now recalibrated itselfto the new flow rate. The "Flow ok" LED will again light and theset-point will automatically be re-set at the 50% of flowpoint.
