Overview
The Omega Engineering DP-F64 analog input rate indicator is a compact, 1/8 DIN panel-mount instrument built for accurate flow rate measurement and monitoring in industrial control systems. This microprocessor-based rate indicator accepts standard analog inputs (4–20 mA, 0–20 mA, 0–5 V, or 1–5 V) and displays real-time flow rate data on a 6-digit LED display. Operating at 110V, the DP-F64 integrates easily into existing process control loops for applications requiring continuous rate monitoring without totalization display.
Key Features
- 6-digit LED display with selectable engineering units and floating decimal point
- Accepts multiple analog input ranges: 4–20 mA, 0–20 mA, 0–5 V, or 1–5 V
- Front-panel scalable from 0 to 59,999 without internal adjustments
- 110V AC power input for standard industrial electrical systems
- Compact 1/8 DIN form factor for space-constrained panel installations
- Optional dual 5 A relays for rate alarm or batching control
