Meter orientation, Vertical placement, Horizontal placement – Badger Meter M-Series M5000 User Manual

Meter Orientation
Mag meters can operate accurately in any pipeline orientation and can measure volumetric flow in forward and reverse
directions .
OTEE:
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 .
OTEE:
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 electrode mounted in the pipe
is not covered by fluid for five seconds, the meter will
display an Empty Pipe Detection condition . The meter
will send out an error message and stop measuring
flow . When the electrode is again covered with fluid,
the error message disappears and the meter will begin
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 three diameters of
straight pipe is required on the inlet (upstream) side . Two
diameters are required on the outlet (downstream) side .
