Dynasonics TFXP Series Transit Time Ultrasonic Flow Meter - Manual (Page 58)

Rev. 5/09
-3.20- TFXP
Also included with the data logging package is a stand-alone power
supply for use when the data logger is not installed in the TFXP.
Most RS232C serial ports do not supply enough power to enable
data retrieval from the data logger module. When accessing data
stored in the logger without it being connected to the TFXP, this
special power supply should be used.
See Part 4 for details regarding operation of the Data Logger and
the ULTRALINK™ software utility.
