Definitions
- Bothersome mineral materials found in fluids would include calcium bicarbonate, calcium carbonate, calcium sulphate, magnesium sulphate, sodium salts, silica, alumina, iron and manganese salts and free sulphur.
- the rod is additionally provided with a groove on the external surface of the rod.
- the rod's dimensions are ideally chosen to prevent any significant drop in the flow rate, or pressure, of the fluid flowing through the conduit 12, 112. It will also be appreciated that, as the diameter of the rod increases, the rods become quite massive and may become an impediment or restriction to flow through the conduit. Accordingly, it may be desirable that a longitudinally extending passageway is formed in the rod (as is shown in Figure 3) to provide an additional fluid flow channel and, at the same time, an additional surface area.

Abstract
L'invention concerne une tige allongée (10) conçue pour évaluer le dépôt sur un conduit (12), cette tige (10) étant adaptée pour être insérée et placée dans le conduit (12) et possédant une rainure (34) sensiblement hélicoïdale, s'étendant longitudinalement. Lorsque la tige (10) n'est pas creuse, la rainure (34) se trouve sur une surface externe de cette tige (10). Dans une variante, lorsque la tige est creuse, la rainure est située sur une surface interne de la tige et la tige est éventuellement pourvue d'une rainure supplémentaire sur sa surface externe.
