Description
Description
The FSW-420/30 Seriesmonitors your relative flowrate for applications where theactual flow rate is not important.The FSW-420/30 series is easy toinstall and use. Just put it into thepipe and it’s ready to go. TheFSW-420/30 series sets yourpresent flow-rate at 100% at powerup. Relative flow rate is indicatedby the 7 LED lights. When the flowrate drops to 50%, an alarm goesoff. If you prefer, you can adjustthe alarm point to fit your needs.A green output indicating LED isalso included.
