Dynasonics DXN Portable Ultrasonic Measurement System - Manual (Page 7)

QUICK-START OPERATING INSTRUCTIONS
WARNING
NOT FOLLOWING THE INSTRUCTIONS PROPERLY MAY IMPAIR SAFETY OF EQUIPMENT AND/OR PERSONNEL.
CAUTION
IF THE DXN IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, THE PROTECTION PROVIDED BY THE
EQUIPMENT MAY BE IMPAIRED.
This manual contains detailed operating instructions for all aspects of the DXN instrument. The following condensed
instructions are provided to assist the operator in getting the instrument started up and running as quickly as possible. This
pertains to basic operation only. If specific instrument features are to be used or if the installer is unfamiliar with this type of
instrument, see the appropriate section in the manual for complete details.
TRANSDUCER LOCATION
1. In general, select a mounting location on the piping system with a minimum of 10 pipe diameters (10 ×
the pipe inside diameter) of straight pipe upstream and 5 straight diameters downstream. See Table 1 for
additional configurations.
2. If the application requires DTTN or DTTL transit time transducers select a mounting method for the transducers
based on pipe size and type. See Table 1 . Transit time transducer configurations are illustrated in Figure 2 .
NOTE: N
Transit time setups require information supplied by the DXN meter itself so it will be necessary to power on the unit,
at least temporarily, to obtain the setup information.
3. For transit time operation, enter the following data into the DXN transmitter via the touchscreen software utility:
1 Transducer mounting method 5 Pipe liner thickness 9 Fluid type
2 Pipe O.D. (Outside Diameter) 6 Pipe liner material 10 Fluid sound speed*
3 Pipe wall thickness 7 Pipe sound speed* 11 Fluid viscosity*
4 Pipe material 8 Pipe relative roughness* 12 Fluid specific gravity*
NOTE: N * Nominal values for these parameters are included within the DXN operating system. The nominal values may be
used as they appear or may be modified if the exact system values are known.
