The GE Panametrics AquaTrans UTX878 ultrasonic flow meter combines the simplicity of a loop-powered flow meter installation with proven, advanced clamp-on ultrasonic flow transmitter technology. The Panametrics AquaTrans UTX878 provides customers with an economical solution for flow measurement in pipes up to 16 in (400 mm).
Loop-powered measurement devices have increased in popularity in the recent past because of the simplicity of their installation. A single cable to the flow 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 GE Panametrics AquaTrans UTX878 ultrasonic flow meter to function as a loop-powered meter.
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.
The GE Panametrics AquaTrans UTX878 is a loop-powered, full-featured clamp-on ultrasonic flow meter system for a flow measurement of:
