7.1.2 Connections, accessories and assembly
Direct connection of ULTRAFLOW ® is only permitted to Kamstrup MULTICAL® calculators on terminals 11-9-10, as shown
in paragraph 7.7 Electrical connections . Connection to other calculator types requires the use of a Pulse Transmitter or
Pulse Divider to obtain galvanic separation between ULTRAFLOW® and the calculator.
Note: Check that the meter factor is the same on the flow sensor and the calculator and use a Pulse Divider if this is not
the case.
7.1.2.1 Couplings and mounting of temperature sensors
Correct flow sensor position (inlet or outlet) appears from the front label/display of MULTICAL®. When ULTRAFLOW® is
connected to another calculator, ULTRAFLOW® can be used for both inlet and outlet. Crucial is the coding of the
calculator. The flow direction of ULTRAFLOW® is indicated by arrows on the flow sensor. Couplings and gaskets for
couplings as well as flange gaskets up to and including DN80 are suitable for both PN16 and PN25. Flange gaskets DN100
and DN125 are suitable for PN25 only due to their physical dimension. Couplings and gaskets are mounted as shown in
Figure 15 .
Note: In connection with G¾Bx110 mm and G1Bx110 mm, it must be checked that the thread run-out is sufficient.

Some variants of ULTRAFLOW® 54/34 allow the mounting of a short direct temperature sensor in the flow sensor (see
Figure 15 ). Short direct temperature sensors are suitable for both PN16 and PN25 installations. When exchanging a
separately verified temperature sensor set, always use a new gasket 2210-131 at sensor assembly. If the temperature
sensor is not mounted in the flow sensor, a blind plug with O-ring, 3130-262, is used instead. The blind plug with O-ring
is also suitable for both PN16 and PN25.
When the installation has been completed, water flow can be turned on. The valve on the meter's inlet side must be
opened first.
