The FL-1200 flowmeters provide
a low-cost means of flow rate
indication. They are designed for
applications where precise accuracy
requirements for metering are not
imperative. These meters are ideal
for purge service, sealed oil
systems, bearing lubrication,
cooling water indication, and other
associated applications.
