Panametrics AquaTrans AT868 Ultrasonic Flow Meter

GE Infrastructure Sensing’s AT868 ultrasonic flow transmitter combines state-of-the-art 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 all-digital AT868 has no moving parts and requires minimal maintenance. An onboard microprocessor uses patented Correlation TransitTime™ technology for long-term, drift-free operation. Automatic adjustment to changing fluid properties and dynamically configured operating software simplify programming. Transit-Time Flow Measurement Technique The transit-time technique uses a pair of transducers with each transducer sending and receiving coded ultrasonic signals through the fluid. When the fluid is flowing, signal transit-time in the downstream direction is shorter than in the upstream direction; the difference between these transit times is proportional to the flow velocity. The AT 868 measures
