	Optical beam interruption? weigh them after they have fallen for a set time? what are the balls made of? When you say 'micro' how small are they? John. __________________ A little knowledge is a dangerous thing - Googling is far worse!

	Would take a lot of optics if the balls are really small and the area measured large. __________________ If you never do anything you never have problems.

	True, but we are only guessing at what the OP is doing... As per usual it seems the OP is a 'hit and run' questioner!! __________________ A little knowledge is a dangerous thing - Googling is far worse!

	load cells mounted to the holding container. weight scale to measure lost of weight over time in the holding container. __________________ Life is not a journey to the grave with the intention of arriving in a pretty, pristine body but rather to come sliding in sideways, all used up and exclaiming, "Wow, what a ride!"

	While technically not a freefall, a flowmeter can weigh the product stream and only divert a short distance. A curved chute is suspended by a loadcell and measures the centripetal force required to accelerate the product horizontally. One good meter is the CentriFlow^®manufactured by Eastern Instruments. http://easterninstruments.com/products/centriflow.html Regards, Delmar Schmidt Melfi Technologies Houston http://www.melfitechnologies.com/ __________________ Specializing in Dynamic Weighing Systems for Powder and Bulk Solids Handling

	OK I'll bite. What is a microball? Is it something used to play micro football?
