Abstract
A method of deriving a conclusion of the condition of slurry flow in a non-vertical conduit includes artificially generating a first locally heated spot on an interior surface of the conduit at the invert of the conduit and artificially generating a second locally heated spot on the interior surface of the conduit at a location angularly spaced from the first heated spot at an angular spacing of at least 90°. The temperatures of the heated spots are measured, obtaining first and second temperature values T, T. Electronically generated signals carrying the values T, Tare communicated to an electronic computing device. The computing device automatically calculates a first temperature difference Tminus Tand automatically derives a conclusion of the condition of slurry flow prevailing in the conduit based on the relationship between the value of the first temperature difference and a first reference parameter.
