production of wallboard / drywall, gypsum rock is ground into powder, then mixed
into a slurry which is then used to form drywall board. In the fabrication of
composite decking, railing and fencing products, reclaimed wood and recycled
polyethylene are combined into durable outdoor building products. In these and
virtually any other building material manufacturing process, level controls of
various types are required to maintain an efficient cost effective operation.
processing plants commonly have large vessels or sections called units that are
interconnected by piping or other material-moving equipment which can carry
streams of material. Such material streams include liquids, solids or slurries.
Explosives are chemicals, but unlike other
chemicals, most explosives detonate rather than burn. A detonation is a very
rapid chemical reaction using oxygen that is contained in the material rather
than in the air. In a detonation, the chemical reaction releases gases that
rapidly expand and give off energy as they become hot.
A power plant is an industrial
facility for the generation of electric power through the successive conversion
of energy. For example, in a coal fired plant the chemical energy stored in coal
and the oxygen in the air is converted successively into thermal energy,
mechanical energy and, finally, electrical energy for distribution across a wide
geographic area. Prior to use,
coal silos may be used to maintain and/or
control the inventory. When coal is burned, it creates an ash that if not
controlled can fly up the stack into the atmosphere; hence,

processing plants, including bottling, canning, grain and dry goods processing,
all require level controls to prevent overflow, to determine low levels or empty
tanks, to maintain consistent recipes in mix kettles, and to provide continuous
monitoring of vessels where there is a need to have an accurate account of the
contents. Sanitary Level controls with
fittings are often the required connection.
Grains and Milling
there are only two things that happen in a flour roller mill: grinding and
separating. Before wheat can be milled into flour, it must first be cleaned and
conditioned to remove foreign material and poor quality or infested kernels. The
separation by size, grade, etc. at each stage of the milling process creates
many dozens of "streams" which wind their way through the mill. In the end, the
various streams are blended and mixed to make various grades of flour, then
treated with the addition of malted barley, bleaching agents, enrichments, etc.
before packaging. Level measurement is used to control and maintain inventory in
the storage silos and bins that contain: wheat, additive ingredients,
intermediate by products, and the final product flour.
SmartSonic™ for bulk
solids is the level transmitter of choice for milling and grain
applications and the NULL-KOTE™
level switch is ideal to prevent spills.

Oil and Gas
Water and Wastewater
Water treatment and handling operations, both clean water (drinking) and dirty water (wastewater) require level control throughout the facility including:
sumps and lift stations,
water towers, chemical tanks,
run-dry pump detection, and
open channel flow.
