ABSTRACT:
A pneumatic or electrical signal indicating the flow mass of a fine-grained fuel suspended in a carrier gas is produced by computer means. The input for the computer is constituted by the quantity determined for the volume of the carrier gas and the quantity determined for the density of the carrier gas together with the quantity determined as the specific weight of the fuel and the quantity determined by a radiometric measurement of the total density of the fuel and carrier gas flow. The computer is programmed to produce the above signal on the basis of a mathematical relationship defined in the above text. A valve controlling the feed of fuel into a gasifier is operated by the signal produced by the computer.
