DPF-521-522-Series

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 manufactuers 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.
