4. Calculator with two flow sensors
MULTICAL® 601/602/801 can be used in various applications with two flow
sensors, e.g. leak surveillance or open systems. When two ULTRAFLOW are direct
connected to one MULTICAL® 601/602/801, 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.
•
Forward and return pipes are closely electrically coupled
•
No welded joints occur
In installations where the electric coupling cannot be carried out, or where
welding in the pipe system can occur, one ULTRAFLOW® must be mounted with a
galvanically separated output module and also a supply of its own.
•
Forward and return pipes are not necessarily closely coupled
•
Electric welding *) can occur
*) Electric welding must always be carried out with the earth pole closest to the
welding point. Damage to meters due to welding is not comprised by Kamstrup’s
factory guarantee.
5. Operational check
Carry out an operational check when the complete meter (flow sensor and
calculator) has been installed and connected. Open thermo regulators and cocks to
establish water flow through the installation. Activate the top key of the calculator
and check that the displayed values for temperatures and water flow are credible
values.
