New Way To Weigh Grain
This new way to weigh grain without having to run it over a weigh scale, is said to be accurate within ?1%. It measures grain by flow - just like a gas pump measures gas - giving you an accurate, continuous reading of the amount of grain being elevated in or out of your bins.
"To our knowledge, it's the only device in the world which can accurately measure the rate of mass flow as it's moving. It has many industrial applications but we're zeroing in first on its application to agriculture. It's an exciting new way to accurately weigh grain," says Dennis Holdsworth, president of DWH Engineering Co., Dover, Mass., a consulting engineering firm which developed the first-of-its-kind grain flow monitor.
The "little black box" is called the AccuMass and consists of a combination chute and monitor. Installed at the top of an elevator leg, for example, it accurately measures all grain going in or coming out of bins. The sensor converts the amount of grain flow into lbs., then flashes this information to a monitor which gives an instant reading in bushels. One dial measures bushels in the load coming in or going out, and another keeps tab on the total inventory of all loads.
Retail cost of the unit slated for commercial production on a limited basis early this year is expected to be right at $1,500. "The AccuMass measuring device does not restrict the flow of grain in any way," Holdsworth points out. "While it is highly accurate so far as the needs of farmers are concerned, it is not designed for the legal trade."
Holdsworth says the first on-farm installation of the new way to measure grain was made in Canada on the Wes Magiro farm near Woodstock, Ont. It was engineered and installed by Wes' brother Larry, who is marketing the device in Canada. "The big advantage to farmers is that, 'with this new measuring system, they don't have to take someone else's word on the amount of grain shipped. They can also use it to accurately check crop yields," Larry told FARM SHOW.
