Panametrics PT878GC

Operation and performance
Fluid types	Acoustically conductive gases with minimum pressure requirements. See installation requirements table.
Pipe size ranges	0.75 in to 12 in (20 mm to 300 mm) with TransPort PT878GC-01 electronics 4 in to 24 in (100 mm to 610 mm) and larger with TransPort PT878GC-02 electronics
Pipe wall thickness	Thicker walled pipes require greater gas density. See Installation Requirements Table.
Pipe materials	All metals and plastics. No lined pipes
Flow accuracy (velocity)	For pipes 6 in (150 mm) and smaller: ±2% to 5% of reading typical For pipes over 6 in (150 mm): ±1% to 2% of reading typical Accuracy depends on pipe size and other factors.
Repeatability	±0.2% to 0.5% of reading
Range (bidirectional)	See Installation Requirements Table
Rangeability (overall)	150:1
	Specifications assume a fully developed flow profile (typically 20 diameters upstream and 10 diameters downstream of straight pipe run) and flow velocity greater than 5 ft/s (1.5 m/s). Pipes 2 inches (50 mm) or less require a minimum of 10 ft (3 m) of continuous straight run without flanges, welds or coupling joints.
Measurement parameters	Standard and actual volumetric flow, flow velocity and mass flow
