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:
“On the idle hill of summer,
Sleepy with the flow of streams,”
—A.E. (Alfred Edward)
“...there was the annual Fourth of July picketing at Independence Hall in Philadelphia. ...I thought it was ridiculous to have to go there in a skirt. But I did it anyway because it was something that might possibly have an effect. I remember walking around in my little white blouse and skirt and tourists standing there eating their ice cream cones and watching us like the zoo had opened.”
—Martha Shelley, U.S. author and social activist. As quoted in Making History, part 3, by Eric Marcus (1992)
