V.
Maintenance
a. Global Water recommends verifying the sensor’s calibration with a
sounder or other measuring device once every 6 months.
b. The screen on the end of the sensor must be periodically checked for
clogging from mud, sludge, and other debris. Wash the screen with
clean water and/or scrub it gently with a toothbrush. Do not insert
objects through the screen, as this may cause damage to the sensor.
VI.
Trouble Shooting
Issue: Sensor reading incorrectly
a. Verify power source is supplying the correct voltage.
b. Verify that the vent tube has not been kinked or sealed. The sensor
uses this tube to compensate for barometric pressure changes.
c. Clean the sensor following the maintenance instructions.
d. Verify the sensor’s calibration.
Issue: Water in the vent tube
a. If water gets into the vent tube of the cable place it next to a heater for
24 hours to dry the inside of the cable.
