Valid environment for SEN0311 based on A02YYUW

Hello,

I look for a solution to measure the level of liquid (chlore and ph-) in containers of 40-50 liters.
This is to be used in the context of a swimming pool. So regulators are in place to inject chlore and pH- acoording to their monitoring (out of scope of this discussion).
I'm concerned about the following :
- I need to know when the containers are getting empty
- I need to be informed if liquids are consumed too quickly

Note that the sensor would at 50cm above the bottom of the container. When fully filled, the liquid reaches a 40cm level.

I identified this SEN0311 based on A02YYUW to be a good solution candidate in my context.
What about the nature of the  liquids in this context ?

Thanks !
