5.6.5Calibration of the ultrasonic homogenizer

1Assure that the instrument has been calibrated nor- mally. See sections 5.5 through 5.6.4.

2Obtain a 1 to 2 liter representative grab process sample (from a steady

stateprocesscondition)(ultrasonichomogenizeris“off”-powerpotenti- ometerfullycounter-clockwise)fromthesafeventportbyoperating valves V3 and V4. (Caution: be aware of any high process sample pressurewhencollectingthesampleoutofthisvent).

3Blend this process sample (500 cc) for 2 minutes in the waring blender fromthecalibrationkitsimilarlytotheproceduregiveninthecalibration section 5.5 through 5.6.4.

5Within a short time period of a few minutes assuming the process oil concentration hasnot changed, adjust homogenizeras follows tothe same steady state process sample reading as obtained for the calibration reading of the blended sample. This must be done at the prescribed factorysampleflowratesetting.

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 propercalibrationandoilresponseoftheinstrument.

6adjust 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
