4.3 Pulse Transmitter / Pulse Divider and Cable Extender Box
4.3.1 Introduction
Depending on the application of ULTRAFLOW
®
, galvanic separation, adaptation of meter factor to a foreign
calculator or longer cables between ULTRAFLOW
®
and MULTICAL
®
might become necessary. Pulse Transmitter,
Pulse Divider and Cable Extender Box are electronic devices, which are mounted between ULTRAFLOW
®
and the
calculator, and which can provide different technical solutions for these purposes, respectively.
Pulse Transmitter and Pulse Divider are delivered with built-in supply for ULTRAFLOW
®
. By default Pulse
Transmitter/Pulse Divider is powered by a built-in battery. Alternatively, Pulse Transmitter/Pulse Divider is
externally powered by 24 VAC or 230 VAC.
Pulse Transmitter and Pulse Divider are delivered with galvanic separated output module. See
paragraph 4.3.3
below.
Galvanic separation is used in the following situations:
1) For flow sensor no. 2 in connection with MULTICAL
®
. If two flow sensors are used together with
MULTICAL
®
, one must be galvanic separated.
For further info, see
paragraph 7.7.3 Calculator with two flow sensors
.
2) If ULTRAFLOW
®
is connected to other equipment/foreign calculators.
Note: Due to galvanic separation flow-info is not possible if Pulse Transmitter or Pulse Divider is used.
When a Pulse Transmitter or Pulse Divider is connected between ULTRAFLOW
®
and MULTICAL
®
, the cable length can
be extended depending on the calculator up to 100 m. For further info, see paragraphs 4.3.2 and 4.3.3 .
In cases, where galvanic separation is not necessary, and flow-info is desired, the Cable Extender Box allows
prolongation of the cable length between ULTRAFLOW
®
and MULTICAL
®
of up to max. 30 m. For further info, see
paragraph 4.3.7 .
