3D data:

3D data needs to be collected in order to determine the dimensions and features of an object. The collected data results from the extraction of depth information taken from the shots of the objects observed. These are spatial data, which describe the distance of pixels relative to the sensor. Depending on the procedure, they can be won in various ways: by runtime measurement of light or sound between sensor and object, the evaluation of corresponding pictures or by an analysis of the projected patterns.


3D sensors:

Sensors, which collect three-dimensional data of objects.


Alibi memory:

An integrated, verifiable memory within a device for storing measurement results in a tamper-proof manner.



Camera sensors:

Many of the worldwide integrated products of AKL-tec work with camera sensors and modern digital image processing, in order to enable an accurate documentation for the customer.

CEP companies:

Courier, express and parcel services

Contour testing:

The precise contour detection serves the assessment, if a contour is in accordance with certain specifications such as the size of an aircraft interior or the maximum dimensions of a storage bay.


Cross Docking application:

Cross docking characterizes a type of merchandise delivery, where the goods are pre-picked and do not need a longer storage.


Dimension weight:

Dimension weight, also called volumetric weight, is a practical value in order to evaluate the costs of a consignment in air cargo (partially also in other fields). Logistic suppliers, airlines and shipping companies as well as parcel services determine the dimension weight for each transport in order to charge light but rather big, voluminous consignments appropriately at a higher price. Example: 1m3= 166 kg taxable weight (air cargo).


European Measuring Instruments Directive (MID):

The MID 2004/22/EG was updated by the revised version 2014/32/EU at the 20.04.2016 and supplemented by 2015/13/EU. The law stipulates, how measuring devices have to be manufactured and conformity assessed (conformity assessment replaces the first calibration) as well as its placing on the market (transition between manufacturer and user).


Freight measurement:

The freight measurement is an important component both for the customer settlement and for the cargo capacity for trucks, airplanes and ships. Depending on the measurement device, space requirement and weight of the package can be determined.


Freight volume-measuring device:

The freight volume-measuring device APACHE of AKL-tec measures cargoes around the globe since 1996. Wrongly declared, too heavy or bulky cargoes are recognized quickly due to the exact measurement of weight and volume. The results are documented seamlessly with pictures, weights and dimensions.


German Weights and Measure Act (MessEG):

The law stipulates that measuring devices are not allowed to be used uncalibrated. The precise guidelines are regulated in the Calibration Regulations and directives. The calibration can only be performed in Germany by legally admitted test centers. The measurement and calibration law has to be respected by all measurement device users, who use those within a commercial, an official manner or for the public benefit. This also applies for the usage of measurement results.


Infra-red scanner:

A modern infra-red scanner works in accordance to the so called LiDAR principle (Light detection and ranging). Laser light impulses are sent out and the returned rays from the object are evaluated by the time-of-flight.


Short for irregularly shaped objects or packages (as opposed to regularly formed, e.g. rectangular shaped objects).



Kollo stands for single Cargo.



Logistics automation:

AKL-tec allows for a smooth and trouble-free material flow using conveyer systems, fully-automated storage and retrieval systems as well as complex warehouse management systems.


Less Than Full Truck Load also called part cargo transport. Several part cargos are pooled within a transport vehicle. A part cargo describes a consignment, which does not fill the transport vehicle completely due to its size or certain specifications.


Material flow:

Material flow is the description of the processes during gaining, manufacturing as well as the distribution of goods within set production areas.


Multidimensional Measuring Device


Non-automated scale:

A non-automated scale requires an operator during weighing.



The International Organization of Legal Metrology is an intergovernmental treaty organization, which is specialized in the global harmonization of legal metrology procedures in order to facilitate international trades. The organization makes recommendations, which are recognized within many countries and influence national norms.

OIML R:129:

OIML R:129 is a recommendation, which specifies the metrological and technical requirements for the pattern approval of multidimensional measuring instruments. These instruments are used to determine the dimensions and/or volume of an object for the purpose of calculating charges for postage, freight or storage. The recommendations are recognized globally.



Protrusions describe supernatants. In accordance to OIML R:129 it is assumed that that the core of “Irregs” consists of a cuboid which develops into an “Irregs” due to its protrusions.


The Physikalisch-Technische Bundesanstalt (national metrology institute of the Federal Republic of Germany) deals with scientific as well as technical service tasks. Especially the working party 5.45 is specialized in the accreditation and certification of length measuring machines. Statements in the industry, commerce and trade sector are usually prepared based on length measurement or the combination of area and volume. Measuring devices have to comply with the Directive 2004/22/EG or the measurement and calibration law.


Volume freight:

When the volume is bigger than the bulk weight.



WELMEC is an organization and stands for the European cooperation in the field of legal metrology. The organization is specialized on the harmonization of legal metrology in Europe. It promotes a uniform application of European and international regulations as well as the elimination of trade barriers regarding measurement devices. In addition, the organization supports the exchange of information and records particularities in legal metrology. The WELMEC guidelines have only a recommendatory character and are not restricted nor have they additional technical requirements.
