Problem:<\/strong>
\nAutomotive Engineers needed a reliable flow rate controller for their emissions test stands. These stands test the efficiency of engines using  gasoline at varying temperatures to determine which temperatures produce optimum combustion.<\/p>\n

The flow of gasoline needed to be held at a constant rate as it was warmed by passing over heating coils, the tests would run at 3\u00b0 increments.<\/p>\n

Accurate flow control was required to obtain uniform heating of the gasoline and to ensure the test validity.<\/p>\n

\"Kates<\/a>
Kates Flow Rate Controller<\/figcaption><\/figure>\n

Although pressure regulators, needle valves, rotameters and control valve loops were considered, the Assured Automation <\/a>Kates automatic flow rate controller was chosen for this application.<\/p>\n

This flow rate controller maintained the flow of gasoline over the heating coils at a constant rate, allowing the tests to be successfully run at 3\u00b0 increments, while maintaining an accuracy and repeatability of 1 \u00bd%  of set point regardless of pressure fluctuations. The  automotive engineers also found the unit simple to operate and maintain.<\/p>\n
