Flow Measurement & Totalization Solution – OMEGA DPF64-SQRT | DPF64 Series
Where This Product Is Used
The OMEGA DPF64-SQRT is engineered for demanding industrial environments where accurate flow rate display and totalization are critical. Typical deployment scenarios include:
- Water & Wastewater Treatment Plants – Real-time flow monitoring across influent, effluent, and recirculation lines with square root extraction for differential-pressure transmitters.
- Chemical & Petrochemical Processing – Continuous rate display and batch totalization for reagent dosing, blending, and transfer operations.
- HVAC & Building Automation – Chilled water and steam flow monitoring integrated into BMS panels via pulse or analog inputs.
- Food & Beverage Production – CIP flow verification and ingredient metering where hygienic process control is mandatory.
- Oil & Gas Upstream/Midstream – Wellhead and pipeline flow totalization with dual-power compatibility (110/220 VAC) for remote skid installations.
- Pharmaceutical Manufacturing – Purified water (PW) and WFI loop flow monitoring supporting 21 CFR Part 11 documentation requirements.

Why Engineers Specify This Model
- Square Root Extraction Built-In – Eliminates the need for an external signal conditioner when using orifice plates, venturi tubes, or pitot sensors; the DPF64-SQRT linearizes the DP signal directly.
- Dual-Voltage Power Supply – A single SKU covers both 110 VAC (North America / Japan) and 220 VAC (Europe / Asia) installations, simplifying global procurement and spare-parts inventory.
- Simultaneous Rate + Total Display – Operators read instantaneous flow rate and accumulated total on one instrument without toggling screens, reducing read errors during shift handover.
- Programmable K-Factor – Compatible with virtually any pulse-output flow sensor; no custom firmware required.
- 1/8 DIN Form Factor – Fits standard panel cutouts already present in most control cabinets, minimizing retrofit cost.
- OMEGA Reliability – Backed by OMEGA Engineering’s 60+ year track record in industrial measurement instrumentation.

Application-Specific FAQ
Q: Can the DPF64-SQRT accept a 4–20 mA signal directly from a DP transmitter?
A: The DPF64-SQRT is optimized for pulse/frequency inputs. For 4–20 mA DP transmitters, a frequency converter or a model with analog input (e.g., DPF64-SQRT with optional analog input board) is recommended. Confirm with OMEGA Engineering for your specific transmitter.
Q: Is the square root extraction function defeatable for linear flow sensors?
A: Yes. The square root function is programmable and can be disabled via the front-panel menu, making the DPF64-SQRT suitable for turbine or magnetic meters that already output a linear pulse signal.
Q: What is the maximum pulse input frequency?
A: Refer to the OMEGA DPF64 series datasheet for maximum frequency rating (typically up to 10 kHz for standard models). Contact us if your sensor exceeds this range.
Q: Can this meter be used in a hazardous (classified) area?
A: The standard DPF64-SQRT is not ATEX or IECEx certified. For Zone 1/2 or Division 1/2 installations, a certified barrier or isolator must be used, or consult OMEGA for intrinsically safe variants.
Q: Does Konmask provide a warranty on this product?
A: Yes. Konmask.com offers a 90-day functional warranty on all verified units. Extended warranty and service contracts are available upon request.
