Overview
The Omega DPF64 digital ratemeter is an analog input ratemeter meter engineered for industrial process control and flow measurement applications. Part of the DPF60 Series, this 110VAC panel meter delivers reliable rate-of-flow display with a 6-digit LED display. The meter is factory-configured for rate display only (not totalizer), making it ideal for applications requiring real-time flow rate monitoring without cumulative count functionality.
Key Features
- 6-digit LED display with 13.97mm digit height for clear visibility
- Analog input ratemeter for 0–20 mA and voltage inputs
- 110VAC power supply (isolated 2,500 Vac)
- Fully scalable from 0 to 59,999 flow rate units
- Peak and valley feature captures recent high and low readings
- Two 5 A (@ 250 Vac) control relays for alarm and batch control
- 1/8 DIN panel mount form factor (92 mm × 45 mm cutout)
- NEMA 4X stainless steel enclosure for harsh environments
- Floating decimal point configurable per application
