MFM500 Flow Switch Features ■Full metal housing, no movable parts, no need to maintenance; ■Easy installation, suitable for different tube diameters; ■Switch output, control point setting continuously on panel; ■LED flicker and display flow and switch situation at real time. Brief Introduction MFM500 Flow Switch is able to monitor and control the liquid flowing of the tube at real time, providing switch output signal and display velocity of flow on multi-LED indicators. The monitoring functions are as follow: ■Media flowing, reduce/ increase velocity of flowing; ■Media exist/non-exist; ■Media flowing/stillness; The product could be used for monitoring velocity of flow, flow-cut or prevent pump racing. It is widely used for monitoring velocity of flow and fluid, or protecting the key device when the liquid runoff is failure in various industries. Applications ■Water and electricity industries, pump controlling in Water Distribution System; ■Metal processing industry, controlling flowing value of the refrigerant and the lubricant, liquid pressure and water supply system; ■Iron and steel industries, chemi-industries, pump racing protection and monitoring leaking and the level of the liquid; ■Beverage industries and monitoring purifying process.

Terminal Defination: green green green green yellow red O lights, flow cut or velocity of flow is lower than setti ng value, the relay opens. o ec green green green green yellow red o o when yellow indicator O lights, velocity of flow is equal to setting value, the relay works. o a o green green green green yellow red when yellow and green indicators light, velocity of flow is more than setting value, the more the indicators light, the more the velocity of flow is. Install switch and make the media flowing as the expected velocity of flow. Adjust the screw with screwdriver until the first green...
