Topic - GRX-Q
GRX-Q - Flow measurement
The flow measurement is part of the metrological determination of a volume flow Q or mass flow m=ρ∙Q. This is done as a function of a measuring cross-section A of a closed pipe or an open channel.
GRX-Q - Volumetric measuring method
The volumetric measuring method is based on the measurement of partial quantities of a medium to be measured. The medium flowing through a defined measuring chamber or via an analog rotation of measuring vanes is added up.
GRX-Q - Displacement meter
With the displacement meters, the moving measuring walls are driven by the medium to be measured. The movement is recorded and counted.
GRX-Q - Differential pressure method
Flow measurement using the differential pressure method is frequently used in chemical engineering and similar industries.
GRX-Q - Flowed bodies
In this type of flow measurement, flow is applied to floating bodies, spring disks or flaps. After the differential pressure method, variable area flow measurement is one of the most frequently used methods.
GRX-Q - Magnetic-inductive flow measurement
In magnetic-inductive flow measurement (MID), an electrical voltage is generated by the interaction between the flow velocity of a liquid and a magnetic field. This principle is based on Faraday's law of induction.
GRX-Q - Ultrasonic flow measurement
Ultrasonic flow measurement, also known as the transmission principle, works on the basis of the propagation speed of sound waves, which changes in moving liquids with the flow speed of the transmission medium.
Topic - artificial intelligence (AI)
AI - What is it?
Basically, the term artificial intelligence is a technical misnomer in this context. Artificial intelligence describes the academic endeavors of humans to research the human brain and its performance and to reproduce it with the help of computer-aided methods.
AI - Autonomous production
Production technology is increasingly characterized by the use of computer-aided knowledge management systems. A distinction is made between expert systems that pursue a deductive learning approach and inductive optimization methods.
AI - How do you proceed?
The first step in this context is to start implementation as soon as possible and not to wait until a competitor can present a solution. Because this solution, if it is available at all, certainly cannot simply be copied or purchased at the touch of a button.
AI - opportunities
The opportunities that arise from the successful use of a production environment that is monitored in line with requirements and controlled by artificial intelligence are diverse and often unexpectedly full of potential.
AI - challenges
As already described in Chapter 3 (AI - How to proceed), the algorithms for the successful application of machine learning in production technology require as much good data as possible. Good data is data whose values are generally as correct as possible.
AI - Risks
In addition to the many good opportunities and high potential benefits of artificial intelligence in production technology, there are also risks that need to be considered when implementing such capability tools.
AI - obstacles
The biggest obstacle to the implementation of digitalization technology at present is the often prevailing confusion among decision-makers responsible for production as to how the project should even be approached.
AI - Implementation
The following example demonstrates how a digitalization project can be successfully implemented.
Topic - General production
