For many food manufacturers, raw
materials accounting is a highly
important and frequently discussed
topic. The idea behind this
thought is to measure the exact
amount of delivered raw materials, such
as milk, oil or alcohol, and then precisely
allocate how much is used in each of the
individual production steps. The goal is to
provide as much as transparency as possible
when it comes to the raw materials used in
each and every product – such as cheese
and butter at a dairy operation – and to
be able to create full cost accounting. The
Promass Q Coriolis-based flowmeter from
Endress+Hauser offers food manufacturers
a one-of-a-kind opportunity to optimize
their raw materials accounting with innovative
technology.
Erroneous volume and mass
flow measurements
Volume and mass flow are two commonplace
terms whose meanings can lead to
very stark differences in materials accounting.
In contrast to volume, mass flow exhibits
a constant behavior when subjected to
changing influences such as pressure and
temperature. That’s why the accounting systems

rely on units of mass in many cases.
Many companies nevertheless use volume
measurements, which can lead to unwanted
differences in the raw materials accounts
settlement. But even mass flow measurements
have potential sources of errors that
users have to take into account. In the field,
one of the primary causes of measurement
discrepancies relates to undetected air or
gas entrainment in fluids, which distorts the
measurement value and leads to differences
in the raw materials accounts settlement. To
prevent this from occurring, Meierei Barmstedt
relies on the Promass Q, a Coriolis-based
flowmeter that detects gas entrainment and
lowers the measurement error ratio to nearly
zero.
