					Aerometry plant for verification

The air flow rate is measured by using an ultrasonic method which has been developed at Moscow State Mining University and Which is based on sound vibrations propagation velocity depending upon air flow rate.

Aerometry plant for verification anemometers

Aerometric installation is designed for checking anemometers of different types. The aerometric installation comprises an aerodynamic channel and a control panel. The operation of the installation is based on the reproduction of the air stream velocity unit by generating and measuring of it. Air flow rate control is two-stage, using a thyristor circuit of fan drive control and a remote-controlled butterfly valve.
