in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flowmeter
The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v
and thus the flow rate Q. A is used to amplify the signal voltage, filter it and convert it into
signals for totalizing, recording and output processing.

The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect
of linearity, zero point stability and calibration uncertainty.

Observe without fail the local occupational health and safety regulations.
Any work done on the electrical components of the measuring device may only be carried out by
properly trained specialists.
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
• A shielded 2-wire copper cable is used as the field current cable. The shielding MUST be
connected in the housing of the flow sensor and signal converter.
• The outer shield (60) is connected in the terminal compartment of the flow sensor directly via
the shield and a clip.
• Bending radius of signal and field current cable: 50 mm / 2"
• The following illustration is schematic. The positions of the electrical connection terminals
may vary depending on the housing version.

• The housings of the devices, which are designed to protect the electronic equipment from
dust and moisture, should be kept well closed at all times. Creepage distances and
clearances are dimensioned to VDE 0110 and IEC 60664 for pollution severity 2.
Supply circuits are designed for overvoltage category III and the output circuits for
overvoltage category II.
• Fuse protection (IN 16 A) for the infeed power circuit, and also a separator (switch, circuit
breaker) to isolate the signal converter should be provided for the device in accordance with
applicable regulations.
• To open the cover of the electrical terminal compartment, lightly press in the side walls of the
mains cover 2.
• Flip the mains cover up.
• Connect the power supply.
• Close the mains cover again by flipping it down.
