Votchala pneumotachometer

Votchal pneumotachometers are indispensable devices for testing mechanisms for wear resistance, determining the speed of movement and inertial force of working parts, and the exact time of testing equipment. Devices in this group include: pneumatic vibro-pneumatic mechanisms, pneumatic and electronic vortex tubes of the "Saxophone" type, volumetric rotameters, weight flow meters, accelerometers and needle analyzers.

The operation of these devices is based on the kinetic energy of gases and liquids, namely, the principle of their operation is based on the conservation of mass and energy, the principles of turbulence and the speed of the stationary flow of liquids, gases, powders or fine materials, which make it possible to accurately determine the speed of movement of an object. This also helps when carrying out repair work and debugging equipment.
