If probe is removed from the line for inspection NEVER use sharp or metallic objects such as a knife or screw driver
to clean the antenna, especially the Teflon coated antenna. Do NOT power wash the unit.
Instead, to remove any oil residues for visual inspection use a clean cloth with oil solvent or part washer.
Preferred solvents include, any petroleum solvent such as mineral spirits, xylene, toluene, gasoline, or diesel. Do not
use WD40 or other chemicals.
If you have a question regarding cleaning solvents, please contact KAM CONTROLS directly at +1 713 784 0000, or
email: [email protected]
During inspection, ensure that there are no foreign objects stuck in the probe or attached to the antennas.

CLEANING AND INSPECTION
TROUBLESHOOTING
If OWD data begins to differ slightly or gradually from sampling data and falls outside of acceptable accuracies, this is
most likely caused by drift. The OWD should be recalibrated using the on-line recalibration procedure outlined on page
25.
If OWD data suddenly veers from historical norms or sampling data, it needs to be removed from the line and inspect-
ed using the steps outlined below.
Remove the OWD from the line according to the instructions on page 16 for insertable models and page 18 for
models installed on fast loops and ML Measurement Loops. Clean the OWD sensor according the guidelines
above, and check for any debris in the probe or on the antennas that could affect measurement. Check the condi-
tion of both antennas.
If there is debris clogging the sensor or coating the antennas in any way, this is most likely the cause of any mea-
surement anomalies. Once the OWD has been cleaned, it can be reinstalled. It does not need
recalibration.
If there is no evidence of debris, the OWD must be tested in order to determine the cause of the measurement
error. This requires samples of 100% brine (produced water) and dry oil or oil with a known, low percentage of
water, an RS232 cable (supplied) or an RS232/USB adapter, and a PC equipped with Hyperterminal software.
Connect the OWD to a PC via RS232 or RS232/USB adapter, and turn the power on. Initiate Hyperterminal setup.
For information on setting up Hyperterminal software, see page 22.
Let the OWD sensor warm up for 20 minutes.
Insert the sensor in a bucket with brine (produced water). Probe should remain in brine until a stabilized tempera-
ture is observed. As all water in crude oil has salt, the OWD sensor has already been calibrated for salt water. You
will not get an accurate reading if you use fresh water for testing.
Capture and save screen data according to instructions outlined on page 24.
