Panametrics AT868 Clamp On Flowmeter
- Industry Leading Clamp On Flow Meter Cost Effective
- Dual Channel Versions Available
- Wide range of liquids, 13-7600mm diameter
- IN STOCK. Next Day Delivery
Overview
Please note that the AT868 single channel version has now been discontinued and replaced by the AT600. The dual channel version is still available.
The AT868 flow meter combines state of the art ultrasonic flow measurement capability with a low-cost transmitter package that can be installed right at the process measurement point. It's designed specifically for water and wastewater applications in full pipes.
The AT868 ultrasonic flowmeter is offered with wetted or dry clamp-on transducers for convenience. Wetted transducers offer accuracies better than 1%. The AT868 clamp on flowmeter has no moving parts and requires minimal maintenance. An onboard microprocessor used patented Correlation Transit TimeTM technology for long-term drift-free operation. Automatic adjustment to changing fluid properties and dynamically configured operating software simplify programming.
The AT868 can also be used in conjunction with Heat Meters to enable energy calculations.

Specification
| 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 |

| 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 |
| Additional options | |
| PanaView™ PC-interface software | The AquaTrans AT868 communicates with a PC through a serial interface and Windows® operating systems. Consult the manual for details on sites, logs, and other operations with a PC. |
