Application: Sample streams at several points in deionized water systems for integrated circuit manufacturing to analyze particulate content.
Where In Process?: Pressurized sample stream off main line flow through particle counter and then through Kates Controllers before it is discharged as waste.
Why Flow Rate is Critical?: The flow of the deionized water must be held at a constant through the analyzer to allow it to give reliable light pulses to be scattered off the particles. A varying flow rate changes the scattering amplitude, resulting in an inaccurate size determination.
What Alternatives Were Considered: Monitoring flow with a meter or electronic mass flow sensor to generate an analog signal used to compensate for the variable light pulses with a computer.
Main Reasons for Choosing Kates: Cost, accuracy and simplicity. Met-One, Inc. will begin recommending Kates to their customers as an enhancement to their product.
