Abstract
KMT RPT Inc. is looking to monitor flow rates in their waterjet cutting systems. The systems use ultra high pressure water [up to 60,000 psi] flowing through tubing on a robotic arm. The ultra high pressure water is turned on and off through a valve. The water exits this valve through a small orifice (usually .008") thereby cutting non-metallic material. Problems with leaks, the valve reaction time turning on or off the water and contaminants in the orifice lead to unacceptable flow rates, causing missed cuts, which upset the purchasers of the end product being cut. Implementing a flow meter that signals when the flow rate is not within a desired range will allow for KMT RPT Inc. to better serve their customers.Description
