Reduce energy costs
Tailor-made energy monitoring for steam, air, gas, oil,
water, electricity, heating and cooling

Tracking down potential savings
Global warming, reducing CO 2 emissions and the trend for rising energy prices are issues
no plant operator can ignore. The questions always remain the same:
Do you want …?
• transparency regarding energy fl ows?
• to uncover potential savings?
• to optimize and even increase system and energy effi ciency?
• to track energy fi gures automatically?
• to create forecasts of energy requirements for multiple production units?
• to record energy fl ows and CO 2 emissions in line with ISO 14001?
Do you want to reduce your energy costs in doing so?
If so, you can count on Endress+Hauser completely in regard to “Energy and Cost
Savings”! For effi cient energy monitoring, we offer you everything – all from one source:
• Reliable measuring values as the basis for analyzing energy fl ows
• Intelligent devices for data recording and data transfer
• Made-to-measure software packages for analyzing and evaluating measured energy
data
Only with targeted energy monitoring can the energy consumption and plant effi ciency
be assessed objectively and saving measures initiated. The benefi ts are clear:
• Reduction in energy consumption (typically 5 to 15% is possible)
• Recording energy fl ows with calibrated meters (required by EMAS and ISO 14001)
• No time-consuming reading of measured values
• Reliable triggering of warning messages (limit value not reached/exceeded)
• Simple generation of reports on current energy consumption, profi tability of saving
measures, etc.
Did you know ...?
• that targeted measures can be used
to lower the energy consumption of
a plant typically by 5 to 15%?
• that the use of economizers can
typically increase boiler efficiency
by 2% for every 10 °C? And that at
annual fuel costs of EUR 1 million
this represents a saving of EUR
20 000 per year?
• that electricity accounts for 75%
of the total operating costs for air
compressors?
• that the energy cost of compressed
air goes up approximately 6 to
10% for every unnecessary bar of
pressure?
• that a 3 mm leak in a compressedair
pipe can cause additional costs
of EUR 1100 per year? And that
100 leaks of this size incur annual
additional costs of EUR 110 000?
Data acquisition
1.5 millimeter leak
= additional costs of EUR 275/Year
Optimization
Data analysis
3 millimeter leak
= additional costs of EUR 1100/Year
6 millimeter leak
= additional costs of EUR 4400/Year

You can control only
what you measure
Utilities provide energy for plant operation
in all sectors of industry. Air, steam, fuels,
cooling or heating water are just a few of
the media used. Generating, transporting
and distributing these media requires a
considerable amount of cost and energy.
Therefore, every plant operator’s goal must
be to run and control these processes as
efficiently as possible.
Endress+Hauser, as a single-source supplier
can provide you all the devices you
need to accomplish this. These high-precision
devices – tried and tested in the
field – secure your data as the basis for
optimum energy monitoring.

Endress+Hauser has one of the world’s most comprehensive range of
measurement and control technology products. We supply you with
everything you need to objectively assess energy consumption and
plant efficiency – sophisticated measurement technology including
data transfer through to software for energy monitoring.
Our modular and open energy monitoring system facilitates problemfree
integration of many different components, such as flowmeters,
electricity and gas meters, data loggers, energy computers and recording
devices.
The data is transferred via HART as well as fieldbuses (PROFIBUS,
FOUNDATION Fieldbus, MODBUS) or wirelessly if the measuring
point is difficult to access.

Transparency via precise measurement
You can control only what you measure. The right device installed
correctly at the right place permits the accurate metering of fl ow, pressure,
temperature and other important process values. The outstanding
fi eld accuracy and long-term stability of Endress+Hauser devices form
the basis for all subsequent evaluations and analysis – and therefore
also for planned energy-saving measures.
Intelligent data manager onsite
Very often, the target values determined, such as steam boiler effi ciency,
fuel consumption or pressure loss, need to be not only registered, but
also read and verifi ed onsite directly in the plant. Memograph M has a
variety of functionalities to achieve this:
• Registration and analysis of energy data
• Calculation of characteristic values (e.g. energy consumption,
boiler effi ciency)
• Data visualization on the clear, graphics-compatible display panel
• Data transfer (e.g. via Ethernet, OPC-Server, MODBUS)
• Issuing of alarm messages (limit values exceeded/not reached)
Evaluate energy data – show potential savings
Visualization and evaluation of process data, however, are the real keys
to benefi t fully from measurement technology. The web-based energy
monitoring software we use permits access to the entire monitoring
system in your plant from anywhere via an Intranet or the Internet. In
addition, this software can be used to analyze measurement data and
as the basis for creating energy reports. The individual modules include:
• Energy analysis, e.g. evaluation of the energy consumption and effi -
ciency of compressors, steam boilers, refrigeration systems or pumps;
target/actual comparison, identification of top consumers
• Financial analysis, e.g. consumption costs, budget comparisons (target/actual),
time-based comparisons, profi tability calculation (ROI)
• Reporting: production of tables, graphics (e.g. cumulative curves,
comparative displays), automatic sending of energy reports via email,
etc.
• Deviation analysis also for notifi cations via email or SMS
