1. Instrumentation in the dairy industry
Improve sustainability and milk safety with
high quality measurements

2. Challenges in the dairy industry
Process instrumentation, services and solutions
strengthen your competitiveness
Food safety
Dairy companies align their production processes with product safety and
reliability as a main focus. As a full line supplier of sanitary measurement solutions,
Endress+Hauser supports these efforts with process instrumentation meeting the
stringent requirements of this industry.
Hygienic materials
• Endress+Hauser offers a complete product basket designed and manufactured for the
food & beverage industry using GRAS (Generally Recognized as Safe) materials listed
in CFR21 part 175 through 186.
Hygienic design
• 3-A and EHEDG ensure cleanability for our products
Hygienic process connections
• Endress+Hauser instruments are available with the right process connections
In-line quality control
Sustainability initiatives and production loss reductions can be achieved
by applying innovative in-line quality control points. In addition, production
time can be shortened, plant capacity increased and out off-specification

batches reduced. Therefore, Endress+Hauser instruments provide more
process information:
Mass flow, Viscosity, °Brix, and % Milkfat
Fulfilling the economic task to get the most out of one measuring point, the
Proline Promass Coriolis flowmeters measure mass, temperature, density
and viscosity simultaneously. This opportunity opens up completely new
application fields and can be used to derive other variables such as volume
flow, solid contents, concentrations and complex density functions.
Liquiphant M & FML621: Density measurement
Density measurement in pipes and tanks A transition monitoring Liquiphant M allows an easy to install density
measurement in pipes and tanks. By processing the resonance frequency of
the vibration fork with the Density Computer FML621, you get accurate
and fast monitoring of phase shift or density (concentration can be calculated).
Up to five density measuring points (with temperature compensation) can be
installed in one density computer ensuring fast ROI (Return on Investment).
pH measurement
To establish an in-line pH measurement that detects the smallest deviations of
pH shifts, calibration and measuring procedures have to be reproducible. This
can be realized with the TopCal S CPC310 system which measures, cleans
TopCal S CPC310 & CPA475: and calibrates fully automatically. Used with glass or non-glass pH sensors, it
Fully automated pH measurement can be used in all areas of process and utilities.
