The GE Panametrics TransPort PT878 Portable Liquid Ultrasonic Flowmeter is a highly versatile, self-contained, portable transit-time system with options and accessories to meet all your liquid flow measurement needs. The GE Panametrics TransPort PT878's compact size, lightweight, rechargeable internal battery pack and universal power supply charger make it the ideal go-anywhere flow meter.
The TransPort PT878's patented Correlation Transit-Time™ digital signal processing (DSP) technique greatly increases its signal-to-noise ratio for accurate, drift-free flow measurement in liquids that contain a second phase of entrained solids or gas bubbles. The TransPort PT878 operates in these and other difficult applications where conventional transit time flow meters fail.
The GE Panametrics TransPort PT878 flowmeter also accurately measures flow rate in perfectly clean liquids containing no “scatterers,” where Doppler flow meters cannot work. The TransPort PT878 is suited for all standard transit time applications.

|Operation and Performance
||Acoustically conductive fluids, including most clean liquids, and many liquids with entrained solids or gas bubbles. Maximum void fraction depends on transducer, interrogation carrier frequency, path length and pipe configuration.
||0.5 in to 300 in (12.7 mm to 7.6 m) and larger
|Pipe Wall Thickness
||Up to 3 in (76.2 mm)
||All metals and most plastics. Consult GE for concrete, composite materials, and highly corroded or lined pipes.
|Clamp-On Flow Accuracy (Velocity)
||• Pipe ID>6 in (150 mm): ±1% to 2% of reading typical
• Pipe ID<6 in (150 mm): ±2% to 5% of reading typical
Accuracy depends on pipe size and whether measurement is one-path or two-path. Accuracy to ±0.5% of reading may be achievable with process calibration.
||±0.1% to 0.3% of reading
||–40 to 40 ft/s (–12.2 to 12.2 m/s)
Specifications assume a fully developed flow profile (typically 10 diameters upstream and 5 diameters downstream of straight pipe run) and flow velocity greater than 1 ft/s (0.3 m/s).
