Badger Meter ModMAG M5000 User Manual

Meter Orientation
Mag meters can operate accurately in any pipeline orientation and can measure volumetric flow in forward and reverse
directions, as long as the pipe is completely full.
OTE: N A "Forward Flow" direction arrow is printed on the detector label.
Vertical Placement
Mag meters perform best when placed vertically, with liquid flowing upward and meter electrodes in a closed, full pipe.
Figure 6: Vertical placement
Vertical placement allows the pipe to remain completely full, even in low flow, low pressure applications, and it prevents
solids build-up, sediment deposit and accumulation on the liner and electrodes.
OTE: N Carefully observe the “Forward Flow” label on the meter body and install the meter accordingly. When installed
vertically, rotate amplifier so that cable glands are facing down.
Horizontal Placement
M5000 meters are equipped with an Empty Pipe
Detection feature. If an empty pipe electrode mounted
in the pipe is not covered by fluid for five seconds, the
meter displays an Empty Pipe Detection condition. The
meter sends out an error message and stops measuring
flow. When the electrode is again covered with fluid,
the error message disappears and the meter resumes
measuring.

Figure 7: Horizontal placement
When installing the meter on a horizontal pipe, mount the detector to the pipe with the flow-measuring electrode axis in a
horizontal plane (three and nine o’clock). This placement helps prevent solids build-up, sediment deposit and accumulation
on the electrodes.
Straight Pipe Requirements
Sufficient straight-pipe runs are required at the
detector inlet and outlet for optimum meter accuracy
and performance. An equivalent of 3…7 diameters of
straight pipe is required on the inlet (upstream) side to
provide a stable flow profile. Two diameters are required
on the outlet (downstream) side.
