In many applications, weighing systems for level detection offer a more practical and precise solution than other measuring techniques. With a field-proven sensor program, Anderson-Negele now also offers precise, robust and efficient solutions in this measuring category.

In many process vessels, storage tanks and silos, precise content detection is a particular challenge. Classical measuring systems such as hydrostatic sensors, potentiometric probes, or radar often have their limitations. In some application environments, they are not precise, fast or flexible enough, not practical for technical reasons or not economical.
This is especially the case with:
Process vessels with agitator. Here, sensors that protrude into the medium cannot be installed. The amount of substance is often in motion, creating dynamic shear forces. In such containers, precisely dosed and dynamically added ingredients must also be measurable and controllable in high precision while the process is running. Closed stirring systems often work with negative or positive pressure.
Ingredient exchange containers such as those used for yogurt mixing, which are freely movable. For connection reasons, but also for cost reasons, these cannot be equipped individually with level sensors.
Horizontal tanks. Here, a small change in fill level already causes a significant change in volume; likewise, inherent movement (sloshing) of liquids can make measurement by level sensors difficult. Load cells give more reliable results here.
Tanks for bulk material, in which a surface measurement can be faulty due to irregular mass distribution (formation of piles, funnels, rat holes, etc.). In such tanks or silos, classic continuous level probes are often also not possible due to their size / probe length.
The solution: turn your container into a precision scale
They are new to Anderson-Negele, but have been field-proven for decades: Weighing systems for sanitary and non-sanitary applications, wet and dry goods, process and storage containers.
The inventory control by weight measurement
provides a reliable, highly accurate and consistent display of the actual content, regardless of its movement or distribution.
is completely contact-free, i.e. is not affected by movement, density, consistency or hygiene requirements of the media
Remains unaffected by distribution in the tank, i.e. piling, bridge or rat hole formation
does not require installation on the tank itself, so can ensure precise process control even when tanks are changed frequently.
Thanks to a variety of measuring systems, solutions are available for almost all requirements.
Weighing modules Load Disc
The Load Disc weighing systems dynamically measure the contents of process or storage containers and precisely indicate even the slightest changes in weight. They are firmly bolted between the container feet and the foundation. The very low overall height ensures stability and tilt resistance. Transverse forces caused by agitators are compensated. Their compact, sanitary design with polished surfaces and high water resistace (NEMA / IP) class that they can be cleaned in accordance with sanitary requirements in food or pharmaceutical applications.
In addition to the Load Disc pressure measuring modules, which are mounted between the vessel and the foundation, a tension measuring module is also available . The Tension Cell is inserted between the suspension and the container body in suspended containers.
Applications:
Blending and stirring vessels
Bulk tanks and storage hoppers
For all types of dry products and liquids
Also for corrosive media
Swap vessels for mixing and blending
For interior and exterior installations
For hygienic and non-hygienic applications
Further benefits
Measuring accuracy up to 0.03%
For loads from 100 kg to 45 000 kg (150 to 100 000 lbs)
Vaious models for individually optimized configuration
Long service life due to 4-fold overload protction
Big variety of mounting systems for any application and ambient condition
Easy installation with mounting kit and connection box
Load modules Load Stand
The solid bolting makes Load Stand II a structurally load-bearing integral component and connecting element between the container base and the foundation, and ideal for large containers, tanks and skirted silos.
Thanks to the extremely long service life of the strain gauge cells and their easy replaceability, there is practically no limit to the service life of a Load Stand II.
Applications:
Storage containers for all types of bulk materials and liquids
For all industrial sectors
For indoor and outdoor use
Further benefits
For loads from 11 000 kg to 450 000 kg (25 000 to 1 000 000 lb) per support point
Measuring accuracy up to 0,2 %
Long service life due to the fatique life of > 20 million cycles and 200% overload protection
Seismic rating approved
High signal output for cable length of up to 600 m
Control units for 1 to 120 vessels
Bolt-On Weighing Cells
Microcell® and L-Cell® are extremely long-lasting, reliable, and compact sensors for cost-efficient inventory measurement in all types of vessels, either with a leg support structure or skirted silos. This avoids measurement inaccuracies reliably due to material characteristics like the angle of repose, rat-holing, bridging, moisture content, compaction.
Depending on the vessel type, the sensors are mounted with bolt-on technology on the structural support members and shear beams support or structural skirt.
Applications:
Precise, robust and retrofittable inventory measuring systems for all types of single or multiple containers
For metal substructures or skirted silos
For outdoor and indoor applications
From 35 t total load (vessel plus contents)
Mounting on structural profiles or skirts
Retrofitting and calibration possible at any filling level
Further benefits
Measuring accuracy 3-5%
Long service life due to the fatique life of > 20 million cycles and 200% overload protection
Easy installation with mounting tool kit, materials, and junction box
Control units for 1 to 120 vessels
