Abstract
Injection of particulate materials into industrial processes can be improved through use of a vessel mounted on a weighing device and which is vented through use of two separate and distinct valves. Optionally, a predetermined pressure in the vessel is maintained through use of a pressure transmitter and an on/off mode of operation.
