Velocity measurement for solids
SpeedFlow 2.0
Continous speed measurement for solids usable in free fall and pneumatics
Especially designed for continuous measurement of velocity of solids and particles such as granulates, powders and dusts, which are transported in free fall or in pneumatic transport. Uses triboelectric correlation technology.

| For the assembly of the sensor, the installation location is specified in accordance with the conveyed inlet and outlet paths. The socket is welded on at the specified installation location and then a borehole of 20 mm is drilled through the socket and through the line. The sensor is then adjusted to the wall thickness, inserted and fixed with the help of the coupling nut. The distance between sensor and analysis unit can be a maximum of 300 m. |  |
