Coriolis Mass Flow Meters Provide Net Weight Filling Excellence
Oden is proud to provide an entire family of net weight liquid
fillers which we call NET/MASS. Ranging from our smallest benchtop
units to our largest in-line automatic machines, NET/MASS products
are the world's first complete filler family for net weight filling
using mass flow meters.
It is a curious fact of life that when you measure the filling dose of your volumetric
filler you use a scale and weigh the product! If you stop to think
how hard it would be to fill a graduated cylinder with many liquid
products it may not be so curious that you use a scale, but from
a technical viewpoint it is true that volumetric fillers are accurate
only volumetrically. When the weight of a product, termed its density
- changes, the volumetric dose the filler produces doesn't change
- but the weight of the volumetric filling dose does. So, when you
track the accuracy of your volumetric filler by weight you are trying
to "maintain product weights" by adjusting a filler that has no
idea what is happening to the density of your product. When you
stop to think about it - this does not make a lot of sense. Because
of this problem, NET/MASS does make sense.
If your liquid filling operations are like most, you are experiencing continuing
pressure to reduce overfills, meet tighter regulatory standards,
satisfy growing statistical process control expectations and still
find a way to make your fillers operate across a growing span of
liquid products and fill sizes. What real choices in technology
are available to you to solve these conflicting requirements?
Until NET/MASS, the only net weight in-line fillers available were weigh-cell based
units designed for the pharmaceutical world. Aside from being incredibly
expensive, these machines do not offer the ability to span a large
variation in fill size or liquid characteristics and they are not
typically very fast.
Scale based net weight rotary fillers are at the very high end of
the cost and speed spectrum and so don't make sense for most operations,
and in any event they lack the ability to match the range of flexibility
and versatility found in Oden's state of the art volumetric in-line
GEN4 PRO/FILL® machines. NET/MASS is the clear (but not so obvious)
answer to controlling fill weight problems caused by product changes
during filling without sacrificing the flexibility of the machine
to run virtually any type of liquid and the versatility of the machine
to handle a vast range of containers. NET/MASS can also provide
the rich statistical data yield being demanded of new filling equipment,
and can offer the most sophisticated electronic controls and operator
interfaces (even Wonderware!).
NET/MASS combines the ultramodern versatility and flexibility of Oden's extremely
successful GEN4 PRO/FILL volumetric series with a net weight filling
technology called the Coriolis mass flow meter. The Coriolis mass
meter can measure the mass flow (as opposed to the volumetric flow)
of virtually any liquid. The technology can span a fill weight range
of at least 100:1. This means that you can run a 3 ounce product
on one shift and a gallon fill the next without change parts of
any kind. And, because the mass meter is able to track true liquid
density, the filler produces net weight fills in real time - regardless
of changes in product temperature, viscosity, pressure or specific
gravity.
No matter what liquid filling products world you live in -- household, personal
care, industrial, cosmetic, pharmaceutical, petroleum, chemical
processing, food -- or "not-otherwise-classified" -- NET/MASS
filling technology can open new capabilities for your manufacturing
operations. We don't think we are exaggerating at all when we say
that NET/MASS will be the next revolution in liquid filling.
Another bit of good news - NET/MASS can be retrofit to all Oden GEN4 and GEN2
machines - right now. So - no one gets left behind, and everyone
can benefit from this new technology.
