7.16 OTHER MENU ENTRIES
All other menu entries will operate and be used in the same manner as the transit time flow measure-
ment mode.
7.14 DISPLAY OF “F” AT NO FLOW CONDITIONS
It is normal for the digital display to show an “F” for the no flow condition since the lack of Spectra
information during no flow is the same as a fault condition.
NOTE: Selecting the Operation Adjust menu cell [Zero/Fault Set] allows the option of indicating
Zero Flow rather than a Fault (see paragraph 2.5.4 for details).
7.15 SELECTION OF LIQUID COMPOSITION
The width of the Spectra wave shape is an indication of the depth of penetration of sonic energy into the
flow stream. The % Deviation is a measure of the width of the Spectra and is representative of the
penetration of the sonic beam into the liquid. Select [Slurry] in Application Data for better flow rate in-
dication accuracy when the % Deviation is less than 25 with typical flow conditions. For % Deviations
above 35, select [Liquid]. For applications that continuously have % Deviations between 25 and 35,
proper selection of either [Liquid] or [Slurry] can be confirmed by comparison to a known flow reference.
