Make sure the hazardous area specified on the sensor approval tag is suitable for the
environment in which the sensor will be installed. Failure to comply with the requirements for
intrinsic safety in a hazardous area could result in an explosion.
CAUTION!
Fully close and tighten all housing covers and conduit openings. Improperly sealed housings
can expose electronics to moisture, which can cause measurement error or flowmeter failure.
Inspect and grease all gaskets and O-rings.
