4.2 Installation Notes

The gauge pressure type submersible level transmitter includes a plastic
vent tube which connects the back-pressure cavity of the gauge sensor
to the atmosphere. In the process of installation and operation, care
should be taken that the vent tube be well connected with the
atmosphere. Always be careful that the vent tube is not jammed, and
make sure no water or other liquid flows through the vent tube. Otherwise,
failure to protect the vent tube could result in premature failure of the
transmitter.
