Material delivery system

A method of delivering material through conduits comprising:

• providing material to be transferred;
• automatically introducing pulses of material into the conduit using a pulse control valve while also introducing a stream of air into the conduit using a trim valve to produce slugs of material to move through the conduit in response to a control system connected to said pulse control valve, said trim valve and a pulse velocity sensor;
• monitoring the velocity of the slugs moving through the conduit using said pulse velocity sensor;
• conducting the slugs through the conduit to a hopper loader;
• and
• discharging the material from the hopper loader to a container.
