Go with the Flow - efficient gas flow measurement in cement plants
For the proper operation of equipment in a cement plant, knowing the flow rate is essential. In the past, high temperature and particulate in the gas stream have prevented online gas flow measurement. But the Promecon Air Flow System utilises the particulate to measure the velocity of the gas stream.
The system utilises the triboelectric principle. Electrical signals created by (dust) particle clouds passing each of the upstream/downstream sensors are cross correlated and referenced by their time shift. The digital system requires no calibration, ...Download the whole Article here
