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
