5.6.5 Calibration of the ultrasonic
homogenizer
1 Assure that the instrument has been calibrated nor-
mally. See sections 5.5 through 5.6.4.
2 Obtain a 1 to 2 liter representative grab process sample (from a steady
state process condition) (ultrasonic homogenizer is “off”-power potenti-
ometer fully counter-clockwise) from the safe vent port by operating
valves V3 and V4. (Caution: be aware of any high process sample
pressure when collecting the sample out of this vent).
3 Blend this process sample (500 cc) for 2 minutes in the waring blender
from the calibration kit similarly to the procedure given in the calibration
section 5.5 through 5.6.4.
4 once blended, pore the sample thorough the normal calibration fluid train
to the safe atmospheric vent collection and record the ppm oil reading.
5 Within a short time period of a few minutes assuming the process oil
concentration has not changed, adjust homogenizer as follows to the
same steady state process sample reading as obtained for the calibration
reading of the blended sample. This must be done at the prescribed
factory sample flow rate setting.
Refer to the ultrasonic homogenizer sample flow rate setting set up at the
factory and recorded in the addendum section of this manual for the
proper calibration and oil response of the instrument.
6 adjust and record the “new” ppm oil reading for this power level potenti-
ometer setting (also recorded) to obtain the same ppm oil reading of the
steady state process sample recorded above in item 4.
The homogenizer is now power level calibrated to give the same ppm oil
response as the calibration system while calibrated for the process sample
flowrate response through the ultrasonic homogenizer.
