Ultrasonic flow transmitter

The UTX878 flow ultrasonic transmitter combines the simplicity of a loop-powered meter installation with advanced clamp-on ultrasonic flow transmitter technology.

It provides an economical solution for flow measurement in pipes 15-400 mm. Loop-powered measurement provides simplicity of the installation. A single cable to the meter carries both power to the meter and flow information back to the control system. Low-powered ultrasonic transducer technology, coupled with smart-microprocessor power management, allows the UTX878 to function as a loop-powered meter.

The UTX878 ultrasonic flowmeter applies the Correlation Transit-Time technique for flow measurement using a pair of transducers — each transducer sending and receiving coded ultrasonic signals through the water. When the water 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 UTX878 flowmeter can be clamped onto a pipe and within minutes accurately display flow to within 1.0% of reading; and with process calibration, the meter can achieve a better flow measurement accuracy of 0.5% of reading. Process calibration can be done on site where the flowmeter can be calibrated against a known reference.
