The DPF60 series are digital rate indicators and/or integrating totalizers. They accept inputs of 4-20 mA, 0-20 mA, 0-5 V or 1-5 V and can be scaled for engineering units directly from the IP65 (NEMA 4X) rated front panel without tweaking internal potentiometers.
The rate displays are fully scalable from 0 to 59,999. A peak and valley feature allows the user to call up the high and low recent readings. A square root extracting input is optional on all units for use with differential pressure flowmeters, such as orifice plates and pitot tubes.
The DPF66 allows the user to toggle between rate of flow and total flow (6 digits) from the front panel. The rate display is selectable for units per seconds, minute, or hour, and the totaliser integrates in the same engineering units. The two standard relays can be assigned both to the ratemeter, or the totaliser, or one relay to each for batch control and rate alarm.
The DPF65 allows the user to view just total flow.
The DPF64 allows the user to see just rate of flow.
