MULTICAL® 803 & ULTRAFLOW®
3.5 Installations with two ULTRAFLOW® sensors
MULTICAL® can be used in various applications
with two ULTRAFLOW® sensors, including leak
surveillance and open systems. As a main rule,
when two ULTRAFLOW® sensors are installed
with one MULTICAL®, a close electric coupling
between the two pipes ought to be carried out
on which the two flow sensors are mounted. If
the two pipes are installed in a heat exchanger,
close to the flow sensors, however, the heat
exchanger will provide the necessary electric
coupling.

• Inlet and outlet pipes are closely electrically coupled.
• The parts of the pipe installation that are electrically connected to the flow sensors must both
be subjected to soldering.
In installations where the electric coupling is
not possible or welding

can occur in the pipe
system, the cable from one ULTRAFLOW®
must be led through a Pulse Transmitter to
obtain galvanic separation before the cable is
connected to MULTICAL®.

Electric welding must always be carried out
with the grounding connection closest to
the welding point. Damage to meters due
to welding is not comprised by the factory
guarantee.
