The DPF-520 Series is a batching flow processor
with additional output controls. It is designed for
use with Omega® flowmeters and flow sensors, as
well as other manufactuer’s products which have
frequency output proportional to flow. In addition to
batch functions, the DPF-520 Series indicates flow
rate, and other data in large 9.66 mm (3/8") digits on an
easily-read, backlit display. Units of measure are user
selectable.
An analog output of 4 to 20 mA is available both in
active and passive loop configuration, and in
0 to 5 Vdc or 0 to 10 Vdc outputs, and can be
used in applications such as flow rate logging. Two
programmable pulse scaled outputs are also standard,
and can be used, for example, to provide proportional
chemical feed with a pulse-responsive metering pump.
The housing is supplied with two brackets for wallmount
applications, or the top/bottom housings can be
easily separated and reassembled for panel-mount.
