ModMAG M1000 - Inlet and Outlet Pipe Requirements; Straight Pipe Installation; Meter Orientation; Vertical Pipe Mounting

Inlet and Outlet Pipe
Always install the detectors in front of fittings producing turbulences. If this is not possible, plan for distances greater than 3 ×
DN. Distance should be greater than 2 × DN.

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 10: Vertical placement
Horizontal Placement
M1000 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 11: 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.
