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 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.
