A leader in process analytics
Centered around INGOLD products,
METTLER TOLEDO has established
itself internationally as the leading
supplier of process analytical meas-
urement systems for the parameters
pH, ORP, dissolved oxygen, oxygen
in gases, conductivity, and turbidity
– whether for applications in the
chemical and pharmaceutical Indus-
tries, in biotechnology, the food and
beverage sector or in water and
wastewater treatment facilities.
Ingold Ltd, founded in 1948 by Dr. Werner Ingold, and taken
over by Mettler Ltd. In 1986, is today a core element of the
Mettler-Toledo Process Analytics Division.

the Advantages of INGOLD Measurement Technology
The beer market is currently experi-
encing an intense globalization
process, reflected in escalating
competitive and cost pressure. In
addition to this, there is growing
diversification into new, innovative
beverages that call for maximum
production flexibility. The time to
market is becoming ever shorter,
and product quality has to be guar-

Brewhouse
Inline Measurements in the Brewhouse –
Crucial to the Quality of the Wort
Measurement of the pH
value during mashing
When acidifying the mashing-in
water or when mashing at lower
temperatures, it is advisable to
employ a glass-free ISFET pH elec-
trode. This takes on particular sig-
nificance if the spent grains are to
be sold on the open market.
Consequently, breakable glass
electrodes are wholly inappropriate.
Measurement of the

pH electrode InPro 3253: low main-
tenance requirement, but accurate
due to self-cleaning reference sys-
tem and special membrane glass.
• Retractable housing InTrac 798
Maintenance of pH electrode without
process interruption.
• Transmitter pH 2100 e
Ease of operation and reliability.
• EasyClean systems
Automated cleaning and calibration
of electrodes minimizes mainte-
nance effort.

loops are completed by a user-
friendly transmitter that enables
extremely cost-effective operation
of the measuring point.

Turbidity measurement
in the lauter tun and whirlpool
Turbidity measurements are em-
ployed to optimize filtration of the
lauter tun and mashfilter run-offs,
and/or to document charge trace-
ability at the whirlpool. In line with

can be used to configure and check
out several different sensor units.
On the other hand, transfer of meas-
urement data is realized through a
direct wiring connection between
sensor and control system. This is a
cost-effective alternative for consi-
deration during plant design.

Fermentation and Storage Cellars

Measurement of
dissolved oxygen content
The quality and vitality of the yeast
strongly influence the stability of the
flavor of a beer. Fluctuations during
the yeast cultivation and fermenta-
tion processes can be avoided if
aeration is controlled by inline
oxygen measurement. Correct oxy-
gen concentration during the fer-
mentation process ensures the de-
sired concentration of aromas and
of those substances which prevent

METTLER TOLEDO oxygen meas-
urement instruments are mainte-

functions. This leads to greatly
improved operational performance
and availability of the measuring

criterion as is its fresh flavor.

Measurement of
pH values in wort transfer and
filling lines
To increase operational safety, pH
measurement in these lines pro-
vides a valuable service. The
immediate detection of residual
caustic soda solution or break-
throughs into the product prevents
filling of contaminated end product.

transmitter is easily understood.
METTLER TOLEDO systems facilitate
the initial instruction and training of
personnel. The associated pH elec-
trodes are particularly cost-efficient
due to their extended operational
life.
The economic use of fresh water as well as the multiple
use of cleaning solutions together present a further
basis for achieving overall cost reduction in the strive to
achieve greater efficiency of the brewing process. Here
also, inline systems are of particular help in monitoring
and optimizing the relative sub-processes.
