Abstract
The high temperature particle velocity meter is comprised of a pair of spaced apart conducting portions having disposed on each of their upstream edges a first and second non-conducting portion. The bombardment of the particles on the conducting and non-conducting portions creates charged particles in the pneumatically transported material. These particles discharge an electric current through the conducting portions to respective conductors and then to respective signal generating means. The signal generating means convert the electric discharges to an electronic signal. The electronic signals from each of the signal generating means are fed into a calculating means which calculate the particle velocity of the material based on the respective electronic signals. In another embodiment, the device can be used in a ceramic pipeline or a metal pipeline having its inner surface ceramically lined. In this embodiment, the device does not include the non-conducting portions as the pipe is already non-conducting. An associated method is also disclosed for each type of pipeline.
