Badger Meter ModMAG M-Series M7600 User Manual

Meter Orientation
Mag meters can operate accurately in any pipeline orientation and can measure volumetric flow in forward and reverse
directions.
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.
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.
Figure 5: Vertical placement
Horizontal Placement
The M7600 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 6: 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.
