Series UFX Phase Shift Flow Meters feature advanced Trans-Phase measuring technology, providing accurate and reliable flow velocity as- sessments in closed piping systems. The UFX utilizes a non-invasive transducer which is hand-held or strapped to the outside of a pipe.
CONTROLS AND TERMINOLOGY Transducer Cable Transducer Plug Transducer Jack Display Keypad Transducer Note: The UFX battery compartment is located on the back of the enclosure. Remove the two upper screws to gain access to the battery compartment.
Selecting the proper location for taking a flow measurement is the single most critical step in the operational procedure. The transducer utilized by the UFX flow meter contains two piezoelectric crystals for transmitting and receiving ultrasonic signals through the wall of a pipe. Select a...
To ensure an acoustically conductive path between the transducer face and the prepared pipe surface, a coupling compound is employed. Enclosed with the UFX flow meter is a tube of Dow Corning 111 silicone based grease. This grease is adequate for the majority of installations.
30 seconds be taken to ensure reading stability. The UFX can be turned off by pressing the ON/OFF key on the keypad, or the unit will automatically turn off after approximately 3 minutes of operation.
J. DISPLAY TEST The UFX contains software to verify operation of the individual LCD segments. To run the display test, turn the UFX off. Press and hold the FT/SEC - M/SEC key, then press the ON/OFF key. Release both keys and verify that all segments illustrated in Figure 4 illuminate.
• Erroneous Readings Transducer mounted incorrectly. • Another local ultrasonic instrument is operating at approximately the same frequency as the UFX. • Excessive pipe vibration. • Very viscous (thick) liquids will cause the unit to read lower than actual flow.
