In the electromagnetic measuring principle, the flowing medium is the moving conductor. The
voltage induced (Ue) is proportional to the flow velocity (v) and is supplied to the amplifier by means
of two measuring electrodes. The flow volume (Q) is calculated via the pipe cross-section (A). The DC
magnetic field is created through a switched direct current of alternating polarity.
Formulae for calculation
• Induced voltage Ue = B · L · v
• Volume flow Q = A · v

SafetyIT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any inadvertent
changes to the device settings.
IT security measures in line with operators' security standards and designed to provide additional
protection for the device and device data transfer must be implemented by the operators themselves.
Endress+Hauser can be contacted to provide support in performing this task.

Input signalFieldbuses
To increase the accuracy of certain measured variables or to calculate the corrected volume flow, the
automation system can continuously write different measured values to the measuring device via
Modbus RS485, EtherNet/IP or HART input:
• Process pressure or fluid temperature to increase accuracy (e.g. external values from Cerabar M,
Cerabar S or iTEMP)
• Reference density for calculating the corrected volume flow
