Other Flow Cones
The term Marsh cone is also used in the concrete and oil industries. European standard EN445 and American standard C939 for measuring the flow properties of cement grout mixtures specify a funnel similar to the Marsh cone. Some manufacturers supply devices which they call Marsh cones, with removable tubes with size ranges from 5 to 15 mm. These can be used for quality control by selecting a tube which gives a convenient time, say 30 to 60 seconds.

Famous quotes containing the words flow and/or cones:
“The joys of the evil flow away like a torrent.”
—Jean Racine (1639–1699)
“Here was a little of everything in a small compass to satisfy the wants and the ambition of the woods,... but there seemed to me, as usual, a preponderance of children’s toys,—dogs to bark, and cats to mew, and trumpets to blow, where natives there hardly are yet. As if a child born into the Maine woods, among the pine cones and cedar berries, could not do without such a sugar-man or skipping-jack as the young Rothschild has.”
—Henry David Thoreau (1817–1862)
