METER DESCRIPTION
Badger
® Model M-3000 electromagnetic meters are FM
approved for Class I, Div 2 hazardous locations. To achieve
hazardous location ratings electrodes in the fl ow tube are
Intrinsically Safe, designed according to Factory Mutual (FM)
standards. Those standards limit the amount of energy that
can be sent to electrodes to prevent a spark from occurring.
Empty Pipe Detection
Badger Model M-3000 meters are equipped with an
Empty Pipe Detection feature. Empty Pipe Detection is
accomplished by positioning a third electrode close to the
12 o’clock position. Any time this electrode is not covered by
fl uid, for a minimum of fi ve seconds, the meter displays an
Empty Pipe Detection condition, sends out an error message
if desired, and stops measuring to maintain accuracy. When
the electrode is again covered with fl uid, the error message
disappears and the meter continues measuring.
Amplifi er Mounting Confi guration Options
Two amplifi er-mounting confi guration options are available
to meet a variety of meter placement and environmental
conditions.
Meter Mount Confi guration
The Meter Mount confi guration has the amplifi er mounted
directly on the detector. This compact, self-contained
confi guration minimizes installation wiring.
Meter Mount
Remote Mount Confi guration
Remote Mount confi guration places the amplifi er and its
functions at a location separate from the fl uid fl ow and
detector. This confi guration is necessary in situations where
process fl uid temperature or environment exceeds amplifi er
ratings. A remote mounting bracket is supplied.
Detector and amplifi er are connected by wires, run through
conduit, between junction boxes on the detector and remote
mounted amplifi er. The distance between the detector
junction box and amplifi er junction box can be up to 100 feet
(30m).
This confi guration can also provide a more convenient
amplifi er programming and display placement for monitoring
meter readings.
