The FSW-420 & FSW-430 Series have been discontinued. Please see the FSW6000 & FSW7000 as a possible alternative or contact our Flow Engineering department.
The FSW-420/30 Series
monitors your relative flow
rate for applications where the
actual flow rate is not important.
The FSW-420/30 series is easy to
install and use. Just put it into the
pipe and it’s ready to go. The
FSW-420/30 series sets your
present flow-rate at 100% at power
up. Relative flow rate is indicated
by the 7 LED lights. When the flow
rate drops to 50%, an alarm goes
off. If you prefer, you can adjust
the alarm point to fit your needs.
