Fits liquid flow measurement where you need a Panametrics DigitalFlow DF868 correlation transit-time meter with clamp-on or wetted transducers and wide velocity rangeability.
Key advantages
- Principle — Patented Correlation Transit-Time digital signal processing
- Velocity — −40 to 40 ft/s (−12.2 to 12.2 m/s); rangeability 400:1
- Pipe sizes — Clamp-on 0.5 in to >200 in; wetted 1 to 200 in class
- Accuracy — Typical ±1–2% (>6 in clamp-on); ±0.5% with process calibration
- I/O — Two isolated 0/4–20 mA standard; expandable analog/alarm/frequency options
Typical applications
- Clamp-on liquid flow on large pipes without cutting the line.
- Energy (BTU) metering with optional RTDs.
- Dual-channel / dual-path configurations on two pipes or one pipe.
Selection guide
- Transducers — Clamp-on vs wetted; pipe size/material/lining
- Channels — One-channel standard vs two-channel option
- Outputs — Base dual mA vs expanded I/O
- Power — 100–130/200–265 VAC or optional 12–28 VDC
Common mistakes
- Expecting gas flow capability — DF868 is for liquids.
- Skipping straight-run and coupling requirements on clamp-on installs.
- Quoting ±0.5% without planning process calibration.
When to RFQ / what to tell us
- Liquid, pipe size/material, clamp-on vs wetted.
- Channels, outputs, power; energy metering yes/no.
- Quantity and ship-to.
