Cpacitance or Dielectric Measuring

Tank you all for you kindness and answering to my request. Indeed I'ma chemical engineer and I want to use a special capacitor for measuringthe variation of dielectric constant in a fluidized bed. A fluidizedbed is column in which air or another fluid is entering from bottom andfluidized the fine particles (5 to 500 micrometer) exist in the column. By variation in the particle concentration in the capacitor volume itsdielectric also changed. If we could measure this changing indielectric with a high sampling rate, we could calculate the particleconcentration using convenient equations. But the traditional LCR'shave not enough measurement speed (minimum 2 ms) and we want thesampling frequencies above 5 kHz (measurement speed below 0.2 ms). bywhich type of capacitance meters can I do this?

That's a pretty sad picture you paint. If it's true, it may be in part the aggregated result of stories like the one told by ex-HP Research Scientist "G.S.", after Carly Fiorina took over.

The story has little detail, but it does trigger one's curiosity.

Thanks, - Win
