2.7.2 Installation of weld-on versions
For mounting sensors with weld-on connections, please follow the procedure as follows:
• Mount the sensor completely in the pipeline and spot the weld-on connections to the pipe. This
is necessary to align the mounting bores of the flange.
• Remove the sensor body and the gaskets from the adapters by loosen the screws.
• Weld the adapters completely to the pipe.
• When the pipe is cold again, reinstall the gasket and mount the sensor.

DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
DANGER!
Observe the national regulations for electrical installations!
WARNING!
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.
INFORMATION!
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.
DANGER!
The device must be grounded in accordance with regulations in order to protect personnel
against electric shocks.

4.1 Measuring principle
An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic
field. This magnetic field is generated by a current, flowing through a pair of field coils. Inside of
the fluid, a voltage U is generated:
U = v * k * B * D
U = v * k * B * DU = v * k * B * D
U = v * k * B * D
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flow meter
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 signal converter is used to amplify the signal voltage, filter it and
convert it into signals for totalising, recording and output processing.
