Panametrics AT868 Clamp On Flowmeter

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 configurations
Pipe sizes	Clamp-on transducers: 12.7 mm to 7.6m (0.5 to 300 in.) and larger Wetted transducers: 25.4 mm to 5 m (1 in to 200 in) and larger
Pipe-wall thickness	Up to 76.2 mm (3 in)
Pipe materials	All metals and most plastics. Consult RS Hydro for concrete, composite materials, and highly corroded or lined pipes.
Flow accuracy (velocity)	0.5% of reading (achievable with process calibration)
Typical clamp-on flow accuracy (velocity)	Pipe ID >150 mm (6 in): ±1% to 2% of reading Pipe ID <150 mm (6 in): ±2% to 5% of reading
Typical wetted flow accuracy (velocity)	±1% of reading Accuracy depends on pipe size and installation and whether measurement is one-path or two path.
Repeatability	±0.1% to 0.3% of reading
Range (bidirectional)	-12.2 to 12.2 m/s (-40 to 40 ft/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 0.3 m/s (1 ft/s).
Measurement parameters	Volumetric flow, totalized flow and flow velocity
Electronics
Flow measurement	Patented correlation transit-time mode
Enclosures	Epoxy-coated aluminum weatherproof type 4X/IP66
Dimensions	Standard: Weight 0.9 kg (2 lb), size (h x w x d) 184 mm x 150 mm x 89 mm (7.25 in x 5.9 in x 3.5 in)
Channels	Two channels (for two pipes or two-path averaging)
Display	2-line x 16 character backlit LCD display, configurable to display up to four measurement parameters in sequence
Keypad	Six-button internal keypad
Power supplies	Standard: 85 to 265 VAC, 50/60 Hz Optional: 12 to 28 VDC, ± 5%
Power consumption	20 W maximum
Operating tempe°rature	-10°C to 55°C (14°F to 131°F)
Storage temperature	-40°C to 70°C (-40°F to 158°F)
Standard inputs/outputs	One 0/4 to 20 mA isolated output per channel, 600 Ω maximum load One frequency/pulse rate/totalizer output per channel, optically isolated, 3A maximum, 100 VDC maximum, 1W maximum, from 0.1 to 10 kHz Namur NE043 compliant
Digital interfaces	Standard: RS232 Optional: RS485 (multiuser)
European compliance	System complies with EMC Directive 89/336/EEC, 73/23/ EEC LVD (Installation Category II, Pollution Degree 2) and transducers comply with PED 97/23/EC for DN<25
Clamp-on ultrasonic flow transducers
Temperature ranges	Standard: -40°C to 150°C (-40°F to 302°F) Optional: -200°C to 400°C (-328°F to 752°F) See specific transducer for exact temperature range.
Mountings	Stainless steel chain or strap, welded or magnetic clamping fixtures
Area classifications	Standard: general purpose Optional: weatherproof type 4/IP65 Optional: submersible IP67/68
