Claims17
A measuring cup device for use with a water sprinkler in evaluating sprinkler performance, said device comprising:
- a measuring cup including measurement markings along at least one side thereof and a closed bottom end;
- and
- a plurality of legs, formed integrally with said cup and extending beyond the bottom end of said cup, for supporting the device in an upright position in the ground, said legs including pointed end portions for enabling the legs to be stuck into the ground to support the device.
A stackable device for measuring sprinkler performance, said device comprising:
- a tapered vessel having an angled side wall including measurement markings therealong, an open top, a plurality of flanges extending outwardly from said top, and a closed bottom, and a plurality of legs formed integrally with said vessel and extending downwardly from said flanges of the vessel beyond said bottom, for supporting the device, said vessel and said legs being of such a shape that said device can be stacked on a further said device.
A stackable device for evaluating the performance of a water sprinkler, said device comprising:
- a central tapered cup catching water from a sprinkler and including depth measurement markings along at least one side thereof for measuring the depth of the water caught in said cup;
- said cup including a top edge three integral flanges equally spaced around the top edge and expanding radially outwardly therefrom, said flanges defining a V-shaped terminal edge;
- and
- three legs each formed integrally with one of said flanges and extending downwardly from the corresponding terminal edge so as to define a V-shaped channel, said legs terminating in a pointed end portion for enabling the legs to be stuck into a supporting ground surface.
