In an increasingly urbanized world, construction industry is called upon to serve the needs of human society, such as environmental protection and safety in terms of infrastructure. In this context, a sustainable and ethical development means a close connection between buildings and environment. This connection can be achieved through, for example, the concept of ecological concrete or green concrete,...
The oscillating flowmeters have the characteristic fluid flow — oscillation frequency swirled jet. These types of flowmeters are without moving parts, may be on the principle of constructive: the Vortex flowmeters and the Coanda flowmeters. The Vortex flow meters have as basic principle the Vortex accomplishment around obstacles that are placed against the fluid flow. The resulting vibrations are...
Beeing a part of the no moving parts instruments, differential flow meter are mainly used in the industrial environment, not being found in house hold use. The basic functional principle consists in the appearance of a differential pressure between two points of the flow, if between this comes a flow resistivity object (obstacle, strangulation, elbow). The relationship between pressure and velocity...
