CLEANING AND INSPECTION

Under normal operation, the KAM CHA should not require cleaning, unless pipeline usage is limited to a small
number of products, or products are contaminated with debris, organics, etc. Gasoline products or jet fuel in the
pipeline will clean the CHA without removal.
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

READINGS VERIFICATION

The following steps allow operators to check for proper operation of the KAM CHA's individual signals and
outputs outside of process conditions. To test unit with mineral spirits, fill a clear vessel (beaker, etc.) with
enough mineral spirits to fully submerge the CHA probe–approximately 2.5".
1.
Connect power to the CHA per
instructions on pg. 12 of this manual.
2.
Connect to the RS-485 Serial Port
using a RS485 to USB converter or
RS485 to Serial converter.
3. Place CHA probe in a clear vessel
with mineral spirits (if desired).
4. Configure Modbus software using
the settings on pg. 17 of the manual.
Modbus addresses from 40111 to
5.
40129 should conform to the values
listed in Table 4-1.
