Description
The DPF64-SQRT Omega Analog Input Ratemeter from the DPF60 Series is a digital rate indicator and integrating totalizer that supports input signals such as 4-20 mA, 0-20 mA, 0-5 V, and 1-5 V. It features a 6-digit LED display, with the ability to scale measurements directly via the NEMA 4X (IP66) front panel without internal adjustments. This model includes dual 5 A SPDT relays for rate alarms or batch control and operates within a temperature range of 5°C to 54°C. With ±0.15% FS accuracy, the DPF64 ensures reliable readings for real-time monitoring. Optional square-root extraction allows compatibility with differential pressure flowmeters.
