ROUND UP
Is the medium flowing or not?
To check the flow processes in pipeline systems, flow indicators are frequently required
which give an immediate visible answer to the question: ‘Is the medium flowing or not?’
Kobold, represented locally by Instrotech, has their type DKB flow meter with a ball,
used especially for checking the flow of small quantities of liquids.The method of opera-
tion of this unit is astonishingly simple: the flow makes the white ball ‘dance’ to-and-fro
under the glass dome.
If the flow stagnates, the ball drops back into the rest position out of the field of view.
With this design, it is possible, even in conditions of poor visibility and for cloudy and
dirty media, to have a clear indication of cooling water circulation, lubricant flow, air
supply and other media.The unit’s simple construction has only one moving part, thus
guaranteeing reliable and interruption free function.
Type DKB flow indicator is designed specifically for use horizontally running pipes,
and is offered in sizes from G 1/8 up to G 1. At flow rates as low as 0,05 l/min for water
for example, the ball lifts up and will be visible in the glass dome. In the standard ver-
sion with a brass housing and glass dome made of impact resistant borosilicate glass,
the units are suitable for use in temperatures up to 120°C and pressures up to 6 bar.

New barcode
scanner range
Managing your inventory and tracing as-
sets can be a laborious and time-consum-
ing process, especially in hazardous areas.
Extronics offers a cost-effective solution
to help you out; the new iSCAN range of
intrinsically safe barcode scanners. En-
able your staff to work smart; the iSCAN
range's rapid scan rate records information
quickly and efficiently. Light enough to be
easily carried around yet rugged enough
towithstand being dropped onto concrete,
the iSCAN range provides a practical way
to improve productivity whilst reducing
the risk of errors. ATEX and IECEx Zone
1 certified, the iSCAN range can be safely
used in hazardous areas. The wide scan
line and good read range makes it easy
to scan barcodes in awkward and hard to
reach locations, saving time and allowing
workers to maintain a safe distance. The
iSCAN range can connect with your current
systems to give you better oversight of
your operations, and can also be usedwith
smart devices such as the Rough Pro range
via Bluetooth. Fully scalable, it is available
in several different options, giving you the
flexibility to choose the version that's best
suited for your application. Extech is the
sole agent for Extronics in SouthernAfrica
and will provide local IA certification.

ANALYTICAL INSTRUMENTATION
Improved engineering function for configuring fire and gas systems
Yokogawa Electric Corporation has
developed an enhanced version of the
ProSafe-RS safety instrumented system.
The R4.03.00, includes an improved
engineering function for configuring
Fire and Gas Systems (FGS) and new
operation faceplates for the FGS op-
eration and monitoring screens. These
enhancements make it easier to adopt
and use ProSafe-RS in FGS applications.
In the oil, natural gas, petrochemical,
chemical, and other energy and basic
materials industries, various safety
measures must be taken to prevent ac-
cidents and protect the environment.
This includes the use of a safety instru-
mented system, which can secure plant
safety by functioning as an Emergency
Shutdown system (ESD) that detects
abnormal conditions and safely initiates
emergency shutdowns, and by func-
tioning as an FGS.
Yokogawa’s ProSafe-RS safety instru-
mented system can be integrated with
the CENTUMVP integrated production
control system and is widely used
mainly in ESD applications all over the
world.
Based on an April 2017 Yokogawa
survey, ProSafe-RS is one of the top
selling safety instrumented systems
on the market today. Since releasing
this system in 2005, Yokogawa has
continued to strengthen its functions
to satisfy a variety of customer needs.
In response to the rising need for FGS
solutions, this latest release includes
features that make it easier to adopt and
use this system in such applications.
And by adding a new Input/Output
(I/O) module and enabling the use of
an alternate control network topology,
we are giving our customers a greater
range of choices in their ESD and FGS
applications. Cybersecurity has also
been strengthened.
• Easier adoption and use in FGS ap-
plications
• New I/O module
• Ring network topology
• Improved cybersecurity
