RECOMMENDATIONS
Each application has its priorities. Accordingly, the MiniSonic is particularly flexible and
can be adapted to extreme situations, meaning that many applications are possible.
Each value or text field is filled in by Ultraflux before the final tests and delivery.
Nevertheless, it is advisable to verify them by running through the various menus,
comparing them with files given at the time of order, or with your instructions or particular
choices.
More particularly, geometrical descriptions specific to the site and the choice of scale
are the responsibility of the end user.
During a run-through of the various menus, it is advisable to fill in t
he “Probes / Echoes”
menu first, followed by those related to the Pipe and the Product / Fluid range to obtain a
reliable measurement to be transmitted according to the instructions entered into the
“General” menu.
The data to be entered for Sphere / Pig Detection are very dependent from site
conditions: What kind of Pigs? W
hat flow range …Wrong data can lead MiniSonic to don’t
valid an echo loss as a sphere or a pig.
FINAL CHECKS AND TESTS
Once installation, connections and parameters have been set up, several possible
situations may arise:
Case 1
– The measurement displayed and transmitted meets your expectations.
Case 2
– The measurement operates but may lack accuracy or is unstable.
Case 3
– The measurement is not reliable or the MiniSonic is displaying a Fault.
>
Case 1
: Although everything appears to be OK , check the other values:
The echo or gain level compared to typical values.
- For external probes, a gain exceeding 50 dB reveals certain difficulties such as the
wrong choice of probes, incomplete installation or coupling, rusted pipe, absorbent
fluid …
-
For intrusive probes (gas), the gain level depends on gas pressure.
The ESC mode can decide a high gain margin. Take in account it in your diagnosis.
ESC mode can be used first to automatically set Auto Gain values.
The quality index I.D. is normally close to 100 %.
By default, it indicates several perturbations = electrical interference, passage of
bubbles, highly charged fluid …
In this case, in-depth investigation is advisable (oscilloscope).
The displayed speed of sound should be close to that expected an index of good
control of the geometry or application.
