Mounting requirements in heated or cooled
pipelines
The ambient operating temperature of the Daniel 3410 Series Gas Ultrasonic Flow Meter
electronics (i.e. Flameproof enclosure and Intrinsically safe base enclosure) is -40

F (+60
o
C). If the meter is installed into a pipeline which is heated or cooled outside this
temperature range it is necessary to remove the electronics housing from the meter body (i.e.
Spool piece acting as process fluid conduit) and mount it next to the meter body on a pipe stand
or other rigid structure.

Extended length transducer cables (P/N 2-3-3400-194, 15 ft. long) shall be used to connect the
Daniel 3410 Series Gas Ultrasonic Flow Meter electronics to the transducers installed in the
meter body. The process temperature must also not exceed the operating temperature range of
the transducers. T-11, T-12 and T-21 transducers have an operating range from -4

SURFACE TEMPERATURE HAZARD
The meter body and piping may be extremely hot or cold.
Wear appropriate personal protective equipment when coming in contact with the meter.
Failure to do so may result in injury.
