The Welker Slot Chart
When you need chart-changing reliability.
After years of customer usage in both field and
off-shore operations, not a single major operating
problem has been reported. Automatic chart
changing provides gas transmission companies
with accurate chart data, which results in a greater
amount of billable gas and increased revenues.
The reliability factor of the Welker Slot Chart has
been a remarkable achievement of design and
quality assurance in our chart repertoire. Welker
Slot Charts are used by most of the major gas
transmission companies in the United States and
the market’s continued reliance on our charts is
a testament to the accuracy and reliability of our
product offering.
We print, die-cut and punch our charts with
precision, custom designed equipment. The
accuracy of our chart products is the result of
millions of dollars of investment in state of the
art instruments and equipment. Our financial
investments and commitment to continuous
improvement allow us to provide exceptional
quality and fulfill the most critical requirements
of gas measurement.
Used with the Mullins Dial-O-Graph® Automatic
Chart Changer, our charts with the exclusive
Welker Slot provide fast, accurate and reliable
readings. It can be expensive and frustrating
when charts become jammed or damaged during
the measurement process but the reliability and
durability of our high quality charts will make
these problems an afterthought.
Welker Slot Charts offer scanner ink in two shades,
readout holes, back-printing and overprinting.
Our charts function properly on all scanner and
integrator units.
Dial-O-Graph® is a registered trademark of the Mullins
Manufacturing Company.

Series 77™ Disposable Pens
 Our Graphic Controls Series 77 pens couple
field retrofit with the convenience and reliability of
our Disposable Pens. The pens will quickly convert
1, 2 or 3 pen recorders. They are the ONLY
disposables available for this chart-changer
equipped application.
What makes these pens different? Their shape!
The pen body has been moved away from the
writing tip and just a thin metal stylus extends
down to the chart’s surface. This way, nothing
interferes with the critical chart-changing cycle.
Non Chart-Changing Applications
Series 77™ disposable pens are also
recommended for applications where frequent
pulsation causes writing problems.
To Install
Simply remove the old ink system, connect the
pen to its pen arm and place it on the recorder. The
pen arm’s slotted end allows plenty of room for
adjustment to meet the arc line.
