Flow velocity of solids – SpeedFlow
The SpeedFlow from Envea (formerly SWR) is specifically designed for continuous measurement of the flow velocity of solid materials such as granulates, powders, and dust in metal pipes. The sensor can be mounted in free-fall and pneumatic transport systems. It can be used at speeds starting from 0.75 m/s.
Operation
The SpeedFlow utilizes the triboelectric effect. As solid particles pass by and come into contact with the two sensor rods, a charge transfer occurs. These electrical signals are sent to the correlator, which precisely determines the time delay between the two rods. Since the distance between the rods is predefined (8 mm), the flow speed can be calculated. The output, or the flow velocity, is communicated via a 4-20 mA signal.
