Product Options


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.

The AT868 also has MCERTS status and can be used as a certifiable discharge flow meter for MCERTS. Please contact our sales engineers for pricing for sales and installation.
