FLOW/TEMP/SALINITY SENSOR
The Sensor determines flow by comparing the temperature differ-
ential between the heated and unheated test pads. Salinity is
measured by the two “silver” test pads. These pads should be
kept clean to insure accuracy.
FLOW/TEMP/SALINITY SENSOR REVISION
Current Revisions are HX19 and JX 11
FLOW/TEMP/SALINITY SENSOR CLEANING
Once per year, or as needed, clean the sensor as follows:
1. Remove Flow/Temp/Salinity Sensor.
2. Brush with a mildly abrasive green fiber household
cleaning pad. Contacts should be clean and bright
when
done.
3. Thoroughly rinse the Flow/Temp/Salinity Sensor with
clean tap water. Replace and resume normal operation.
4.
Turn power off and back on to re-calibrate and reset
Flow/Temp/Salinity Sensor.
PROBLEMS:
•
Failure to shut of power.
•
Failure to indicate flow.
•
Incorrect salt indications.
CAUSES:
•
Broken or damaged wires.
•
Calcified sensor(s).
•
Failed electrical component.
•
System not Bonded.
