The AquaTrans UTX878 ultrasonic flow transmitter combines the simplicity of a loop-powered meter installation with proven, advanced clamp-on ultrasonic flow transmitter technology. It provides customers with an economical solution for flow measurement in pipes up to 8 in (200 mm).","Loop Powered","Loop-powered measurement devices have increased in popularity in the recent past because of the simplicity of their installation. A single cable to the meter carries both power to the meter and flow information back to the control system. New low-powered ultrasonic transducer technology, coupled with smart-microprocessor power management, allow the AquaTrans UTX878 to function as a loop-powered meter.","Two-Channel Model","An optional second channel provides the capability to measure flow at a single point to obtain two-path averaging of the flow measurement for increased accuracy.","Transit-Time Flow Measurement Technique","The Correlation 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 AquaTrans UTX878 measures the time difference and uses programmed pipe parameters to determine flow rate and direction.
