SITRANS F M MAGFLO
Electromagnetic flowmeter type MAG 5100 W
Potential equalisation
Potential equalisation is carried out with the
built-in earthing electrodes.
Special attention must be given to systems with
cathodic protection.
By compact mounting:
The transmitter must be supplied through an
isolation transformer. The terminal "PE" must
never be connected.
By remote mounting:
The screen must only be connected at the
sensor end via a 1.5 µF condensator. The
screen must never be connected at both ends.
By isolated sensor:
If above mentioned connections are unaccept-
able the sensor must be isolated from the pipe
work.
