Pulse Transmitter / Pulse Divider and Cable Extender Box
4.3.1
Introduction
Depending on the installation of ULTRAFLOW®, galvanic separation, adaptation of meter factor to a foreign calculator or
a longer cable between ULTRAFLOW® and MULTICAL® can become necessary. Pulse Transmitter, Pulse Divider and Cable
Extender Box are electronic equipment that are installed between ULTRAFLOW® and the calculator and provide various
technical solutions for these purposes.
Pulse Transmitter and Pulse Divider are available with built-in supply for ULTRAFLOW®. By default, Pulse
Transmitter/Pulse Divider is supplied by a built-in battery. Alternatively, Pulse Transmitter/Pulse Divider is externally
supplied by 24 VAC or 230 VAC.
Pulse Transmitter and Pulse Divider are available with galvanically separated output module. See paragraph
below.
Galvanic separation can be used in the following situations:
1)
If a cable length of more than 10 m is required between MULTICAL® and ULTRAFLOW®
2)
For flow sensor no. 2 in connection with MULTICAL®. If two flow sensors are used together with MULTICAL®
and an equipotential connection between the two flow sensors cannot be carried out, one (typically V2)
should be galvanically separated.
For further information, see paragraph
6.12.3 Calculator with two flow
3)
If ULTRAFLOW® is connected to other equipment/foreign calculators, ULTRAFLOW® must be galvanically
separated.
4)
In cases where the electronic signal between ULTRAFLOW® and MULTICAL® is disturbed, galvanic separation
in the Pulse Transmitter may in some cases remedy the problem.
<
Due to the galvanic separation, flow info is not available if Pulse Transmitter or Pulse Divider is used.
When mounting the Pulse Transmitter or Pulse Divider between ULTRAFLOW® and MULTICAL®, the cable length can be
extended up to 100 m depending on the calculator. See paragraphs
and
for more information.
In the case where galvanic separation is not necessary and flow-info is required, the Cable Extender Box enables an
extension of the cable length between ULTRAFLOW® and MULTICAL® up to max 30 m. For more information see
