Flow measurement - Import export

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).

For the generation and production of a spray the knowledge of information like the desired droplet size and its distribution is of fundamental importance. In order to characterise a spray correctly, one has to know the droplet size distribution of the droplets, which were generated out of a given liquid. In many applications it is desired to produce very small droplets. For the design and lay out of inhalers for example, it is necessary to achieve droplet sizes not larger than approximately 10 μm to be absorbed by the lungs. When one designs an atomisation nozzle in view of the desired droplet size distribution, one has to make sure via measurements, that the nozzle is really able the produce the expected droplet size distribution within an acceptable uncertainty range. Besides the droplet size distribution, the droplet velocity is an important parameter since it is a measure of the droplet momentum.

A further area of activity of Suvis is the development and application of modern numerical methods for the calculation (prediction) of flows using CFD in industry, science etc. Our employees are especially trained in view of technical applications of numerical flow simulations. Within the recent years we conducted several projects in the area of multiphase flows. We dealt with applications in the optimisation of processes in chemical engineering, the transport of particles, gas cleaning and particle separation from gases and liquids, and the calculation and optimisation of cyclone separators. We apply powerful commercial software tools like grid generators in order to generate numerical grids using CADdata in a short time for even complex applications. Also, for flow calculations and the evaluation of 3D flow fields we apply powerful software solutions. Furthermore, for certain individual problems we apply codes we have developed our selves.

Another working area of the Suvis GmbH is the field of innovative sensor systems applied to particle and flow measurements taking into account microsystems. We develop novel flow and particle sensor systems for the application in environmental technology, process and mechanical engineering, and automotive technology. Important aspects are robustness and economicalness of the complete sensor system in order to create for the above mentioned application fields practical and affordable solutions. The respective sensor system will be developed as a whole solution. This means besides the hardware set up that we also take care of the evaluation of the sensor signals with our own solutions. We develop from scratch up to prototype level including periphery technology development. Please contact us for a not binding offer. We would like to know more about your challenge!

Over the last few years, we at EP-E have designed and introduced a range of primary standards designed for use in calibration laboratories. As a technology partner of the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany, our solutions are based on the highest standards. The EP gas bell plungers generate a volume flow which is traceable to the SI units length and time. The pistons are driven by a stepper motor via a spindle. In the initial state one piston is fully retracted and the other fully extended. The volume flow can be set with high precision via the piston cross section and the travel speed. At the end of the calibration process, both pistons are in the opposite position to the initial position.

EP Ehrler Prüftechnik manufactures LFEs in the flow rate range from 0.012 to 4000 m³/h. In addition to the standard range, EP offers customer-specific LFEs that are perfectly designed for your application. Suitable inlet and outlet sections and the corresponding mounting kits are available for all sizes for installation in customer applications. The achievable measuring accuracy depends largely on the sensor technology used, in particular the differential pressure sensor. When using high-quality sensors, measuring accuracies of up to 0.5 % MW can be achieved with LFEs in the measuring range of 1:10. In order to cover a very wide measuring range without restrictions in measuring accuracy, LFEs with overlapping flow ranges can be combined in one measuring setup. Alternatively, LFEs with correspondingly lower measurement accuracy can also be calibrated for an extended measurement range up to a maximum of 1:100.
