CAUTION
Transportation hazard
When moving the meter, do not insert the forks of a forklift into the bore.
Inserting the forks may cause the meter to become unstable, resulting in injury or damage
to the bore and sealing face.
CAUTION
Tripping hazard
Clear all obstacles or obstructions from the work area when transporting, installing, or
removing the meter.
Failure to clear the work area may cause injury to personnel.
CAUTION
Escaping fluids hazard
The purchaser of the meter is responsible for the selection of Rosemount components/
seals and materials compatible with the chemical properties of the measurement fluid.
Failure to select suitable meter components/seals may cause escaping fluids, resulting in
injury or equipment damage.

Field hydrostatic pressure testing procedures

Rosemount 3410 Series Ultrasonic Gas Flow Meters may be supplied with T-Slot transducer
assemblies which must be removed from the meter before hydrostatic pressure testing.
T-Slot transducer assemblies are available on 4-inch and larger meters for Rosemount 3410
Series Ultrasonic Gas Flow Meters. The T-Slot assemblies are available on all meter sizes for
the Rosemount JuniorSonic
Rosemount 3410 Series Ultrasonic Gas Flow Meters may instead be supplied with T-200
transducers. With full-metal structure, field hydrostatic pressure test can be done with
T-200 transducer in place.
CAUTION
Leakage or pressure containing parts failure
Use precautions to eliminate hazards to personnel in the event of leakage or failure of the
gas ultrasonic meter pressure containing parts or failure of the test equipment and to
prevent over-pressurization during the test procedure.
Failure to comply may result in injury to personnel or cause damage to the equipment.
