paddlewheel flowmeters monitor flow in a wide variety of
applications. These units will measure water ranges from
0.4 to 8000 GPM (1 to 27000 LPM).
The F-2000 features an easily visible eight-digit LCD
read-out with up to four decimal positions. The meter is
field programable via the front panel touch pad, and the
panel is equipped with a security lockout.
The F-20 0 0 digital flowmeter is designed to
accommodate pipe or wall mount installations, and it
can be installed quickly and efficiently
The insertion-style F-2000 displays flow rate, total
flow, and includes an NPN open collector output for
communication with data loggers, SCADA systems, and
other external devices. BlueWhiteDigiMeterF2000
