5.1 Connection example
Examples of connection of ULTRAFLOW® and MULTICAL® (battery supplied).
ø4.5...6 mm
5.2 Heat meter with two flow sensors
MULTICAL® 602 can be used in various applications with two flow sensors,
including leak surveillance and open systems. When two ULTRAFLOW® are direct
connected to one MULTICAL® 602, a close electric coupling between the two pipes
ought to be carried out as a main rule. 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.

Electrical connection
•
Forward and return pipes are closely electrically coupled
•
No welded joints occur
In installations where the electric coupling is not possible or welding in the pipe
system can occur, the cable from one ULTRAFLOW® must go through a Pulse
Transmitter with galvanic separation before the cable enters MULTICAL® 602.
