ISO 17025 Anemometer Calibration

Particle size measurements are important in various applied sciences and in engineering, for example in fuel burning or in cavitation research as well as in particle size control. In all these applications it necessary to have knowledge about the particle dynamics. To gain that knowledge one has to measure the particle size and its velocity if possible in a noninvasive way with high local and temporal resolutions. A device which makes such measurements possible is the so called PhaseDopplerAnemometer (PDA), which has several advantages. First, it exhibits a large dynamic range from micrometer particles up to sizes in the millimetre range. Then it is very precise and no calibration procedure is necessary. Moreover, it is very robust against optical distortions. In the following the working principle of this flow and particle measurement technique will be explained.

With this anemometer ANE8903 you can measure both the wind speed and the ambient temperature.

Wind speed measurement sensors The device measures wind speed and direction and is powered by its integrated solar panel. It also has a rechargeable lithium battery.

The HPX high-pressure calibrator is a high-precision calibration instrument for pressures between 0 bar and 700 bar. The functional calibrator is supplied in a sturdy carrying case and pressure can be quickly generated manually. It is therefore ideal for use in the field. The pressure is measured by the integrated LEX1 manometer and is both shown on the display and output via the RS485 interface. Additional functions such as zero point resetting, peak and trough pressure value indication and leak measurement make it even easier to take measurements.
