Electromagnetic Flow Meter
The flow directions A or B are clearly shown on the name plate. Default
flow direction is "A".
Pressure loss
The pressure loss can easily be determined, if the nominal pipe diameter is
greater than the MagFlux
® flow sensor. See the diagram below:
0.003
Pressure loss graph
The diagram illustrates that decreasing the internal diameter from 100 mm
(DN) to 80 mm (DO) will cause a pressure loss of 0.003 Bar @3 m/s
