Hi!
We are in the development phase of a project were we would like to use multiple (4pcs) of the FS2012 flow sensors. We would prefer to have them all on the same I2C bus but is that even possible?
As far as we can see there is no way of changing the default I2C address of the sensors (x07).
Hi Marcus!
Thank you for using our flow sensor. The I2C address is fixed in the FS2012 firmware and cannot be changed by the user. As per I2C protocol, we cannot communicate with devices having the same slave address. So, we would suggest you use I2C mux (image shown below) so each sensor can be addressed individually.
For more information, I have shared an application note (regarding I2C Mux); please go through it.

Thanks for the answer. We are already looking at implementing a mux so we probably will go that route.
