Series UXF2 Ultrasonic Flow Converter

Excellent Performance and Easy Operation

Series UXF2 Ultrasonic Flow Converters are paired with Series SX3 detectors in order to utilize the transit-time measuring method. Two ultrasonic sensors are mounted on the pipe exterior, and each transmits an ultrasonic pulse to the opposite sensor. The difference in the transit times of the two waves is used to calculate the flow velocity. This meter is a clamp-on type ultrasonic flowmeter for permanent use and is ideal for clean liquids containing no air bubbles such as pure water. The easy-to-use compact and lightweight design is intended for integration into mechanical devices. The adoption of a sound velocity measurement system, which calculates sound velocity from the transit time, keeps the flowmeter unaffected by the temperature and the pressure of the fluid to be measured. Additionally, with the use of a high-speed transit time processor, the system cycle is 0.2 seconds and applicable to short batch processes.

This series is in the process of being phased out. If you cannot find the range you are looking for, please email: Tech Support for a suggested replacement.

We have purchased a UXF2 Flowmeter. Is there a way to connect the flowmeter to a laptop and run a program to collect data in a spreadsheet? If so, would you be able to provide the required information and program/software.
To communicate to a laptop with the series UXF2, you would need a model that comes with either RS-232C or RS-485 serial communication. Further instructions regarding the serial communication can be found in the manual starting on page 85. The full service manual can be found on this web page under Literature.
