Enhanced pulverized coal mass flow measurement -

2011-8-1  The pulverized coal flow measurement technique by load cell is a flow measurement technique in a indirect way, because there is no intrusive sensor in the pulverized coal pneumatic transportation pipeline. The flow measurement result is obtained by inference through the injection vessel weight decreasing rhythm along the time, in the last minute.
