Product Overview: GE Panametrics PT878
GE Panametrics PT878 – Portable Ultrasonic Liquid Flow Meter
The TransPort PT878 flow meter packs big features into a small, lightweight package. It is a go-anywhere portable meter with a rechargeable internal battery pack and universal power supply charger that is so easy to use that you can make your first flow measurement within just minutes of opening the box.
The PT878 is one of the most powerful portable ultrasonic liquid flow meters available. It measures flow from outside plastic, metal or concrete-lined pipes nonintrusively, so there’s no pressure drop, leaks or contamination. Patented correlation algorithms resolve transit-time signals like no other flow meter and allow the PT878 to measure flow in ultrapure to extremely dirty liquids such as raw sewage and slurries.
The PT878’s built-in datalogger can store more than 100,000 data points and up to 32 sets of site location parameters. An infrared port transfers datalog, site and other files to your PC. Temperature transducers are available for measuring energy flow rate. The rechargeable battery provides six to eight hours of continuous remote operation. A rugged, sealed enclosure provides IP67 submersibility to protect the unit against water damage.

| Operation and Performance | |
| Fluid Types | 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. |
| Pipe Sizes | 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) |
| Pipe Materials | 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. | |
| Repeatability | ±0.1% to 0.3% of reading |
| Range (Bidirectional) | –40 to 40 ft/s (–12.2 to 12.2 m/s) |
| Rangeability (Overall) | 400:1 |
| 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). | |
| Measurement Parameters | Volumetric flow, totalized flow and flow velocity |
| Electronics | |
| Flow Measurement | Patented Correlation Transit-Time mode |
| Enclosure | Submersible IP67 |
| Dimensions | Weight 3 lb (1.36 kg), Size (h x w x d) 9.4 in x 5.5 in x 1.5 in (238 mm x 138 mm x 38 mm) |
| Display | 240 x 200 pixel backlit LCD graphic display |
| Keypad | 25-key rubberized tactile membrane keypad |
| Internal Battery | Rechargeable battery: 9 to 11 hr of continuous operation |
| Battery Charger Input | 100 to 250 VAC, 50/60 Hz, 0.38 A |
| Memory | FLASH memory, field-upgradable |
| Operating Temperature | –4°F to 131°F (–20°C to 55°C) |
