Application Info
7.14DISPLAY 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).
7.15SELECTION 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 the Application Data menu for better flow rate indication accuracy when the % Deviation is less than 25 with typical flow conditions. For % Devia- tions 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.
