 Application: Emissions test stands are used to check the
efficiencies of engines run at different temperatures
with controlled gasoline temperatures to get
optimum combustion.
Where In Process?: The flow of gasoline is held at a constant rate by Kates Controllers as it is warmed by
passing over heating coils to get desired temperature. The tests are run in 3º F increments.
Why Flow Rate is Critical?: Accurate flow control is required
to obtain uniform heating of the gasoline, and
to improve the validity of the test.
What Alternatives Were Considered: Pressure
regulators, needle valves, rotameters and control valve loops.
Main Reasons for Choosing Kates: Accuracy of 1-1/2%
of set point regardless of pressure fluctuations. Simplicity is also a major consideration.
