Laboratories

At the Strata Mechanics Research Institute of the Polish Academy of Sciences, scientific and construction work has long been carried out in connection with the use of anemometric sensors to measure gas flows. The subject of the work is two types of sensors: wing sensors and thermoanemometric sensors. The scientific nature of the Institute’s activities promotes the development of many solutions that are unique in the world. The quality of these solutions and verification of them in various environmental conditions were the basis for the implementation of the developed technologies in professional commercial solutions.

The Strata Mechanics Research Institute of the Polish Academy of Sciences is a manufacturer of anemometers designed for work in gas explosion hazard zones, with particular emphasis on the needs of underground mining plants.

In 2008, the Institute established the Measurement Systems Laboratory, which was included in the quality system in accordance with PN-EN 13980:2002. The laboratory specializes in conducting scientific research in the field of mining aerology. Among other things, wing sensors are used to analyze the distribution of velocity fields in mine workings. This is to obtain the information necessary for computer simulation of three-dimensional flows in safety-critical areas of the ventilation network. In its research, the Laboratory also uses thermoanemometric systems developed at the Flow Metrology Laboratory of IMG PAN.

In addition to scientific and research work, the Laboratory’s tasks include the design, manufacture and implementation, in accordance with the guidelines of Directive 94/9/EC, of Group I Category M1 and Group II Category 1 equipment with the highest level of safety, including wing anemometers, new models of anemometric sensors and other sensors and systems for measuring physical parameters of the atmosphere.

The anemometric sensors are subjected to tests in the wind tunnel of the Institute. Maintaining the highest quality of metrological parameters is guaranteed by close cooperation with the accredited in accordance with the standard PN-EN ISO/IEC 17025:2005 Laboratory for Calibration of the Ventilation Measuring Devices. Each anemometer has a calibration certificate in accordance with European Union regulations.

Laboratory for Calibration of the Ventilation Measuring Devices is a part of the Strata Mechanics Research Institute of the Polish Academy of Sciences in Cracow at 27 Reymonta Street. As a result of research conducted at the Institute related to flow metrology, an aerodynamic tunnel was installed in 1970 (developed at the Faculty of Power and Aeronautical Engineering of the Warsaw University of Technology). Over time, this tunnel underwent extensive modernization, equipped with new measuring instruments, and the range of flow velocities covered was expanded.

In 1993, the Flow Measurements Laboratory of the Mine Ventilation Division was registered at the District Office of Measures in Cracow, authorized to verify anemometers, issue certificates of verification, and mark verified anemometers with a registration mark. In 1997, the Flow Measurements Laboratory of the Mine Ventilation Division participated in interlaboratory comparative measurements for the calibration of anemometers, conducted as part of the international EUROMET program.

In the face of increasing orders for the calibration of anemometers, pressure gauges, barometers, and psychrometers, both from the mining sector and other industries related to ventilation, the director of the Institute decided to establish Laboratory for Calibration of the Ventilation Measuring Devices on May 10, 2004.

Currently, the laboratory has two dedicated rooms. The first one is an aerodynamic tunnel, enabling precise calibration of all types of anemometers for air velocities ranging from 0.15 to 40 m/s. The second room serves as a station for calibrating pressure gauges and barometers.

On September 2, 2008, Laboratory for Calibration of the Ventilation Measuring Devices Instruments received accreditation certificate No. AP 118 issued by the Polish Centre for Accreditation. Accreditation covers calibration in the following areas:

  • Air velocity,
  • Pressure.

Since October 1, 2022, the laboratory has been accredited for determining the constants of pitot tubes.

Laboratory of Optical Measurement Methods

The history of the use of optical methods at Strata Mechanics Research Institute dates back to the 1970s. At that time, a more than 20-year cooperation was established with the (now defunct) Max-Planck Institut für Strommüngsforschung in Göttingen. The results of this cooperation included reciprocal scientific internships carried out by IMG PAN and MPIfS staff. The exchange of ideas and experiences contributed to the deepening of knowledge in fluid mechanics, thermoanemometry and flow visualization.

One of the fruits of this collaboration is the Laboratory of Optical Measurement Methods (LOMP), whose activities focus primarily on the use of optical measurement methods in the mechanics of continuous media. Typical areas of application include gas and liquid tides, displacements and deformations of solids, and multiphase flows.

We offer research and expertise in the field:

  • fluid flow,
  • deformations and displacements of solids,
  • fluid flow in models,
  • Analysis of fast flow/deformation processes of periodic and non-periodic nature,
  • multiphase flows.

The laboratory is equipped with a Closed Circuit Low Velocity Aerodynamic Tunnel (TANPOZ) suitable for measurements using various types of optical methods, including digital Particle Image Velocimetry (PIV).
