Concentration Measurement

Qasim Ahtesham

Hi All,

I am looking to measure the concentration of Calcium chloride solution, in the range of 30-50%. Can anyone please recommend any suitable sensors for this purpose?

Thanks.

I have found this design from TI, but I am not very clear what this A and B represent? I am assuming they are ultra-sonic sensors-if yes, then which model? Here is the link to this document:

I initially started the search with this sensor:

Qasim,

For concentration measurement, please refer our App note:

As for the transducers we typically recommend a 1MHz transducers, a short list of which is in the Application Note: www.ti.com/.../snaa266a.pdf

Thanks Bharat,

Please correct me if I am wrong, but I am assuming that if the solution whose concentration I need to measure is constantly moving/being agitated, this will affect the sensor?

Thanks again.

The ultrasonic solutions do not give accurate results for any medium that has agitations.
