Can I use the WaterGuru SENSE S2 in a pool with a gutter?

The WaterGuru SENSE S2 works best when it is in a skimmer where it can get adequate water flow.

If you have a pool without a skimmer, that has a gutter, the only solution would be to use the Float Ring supplied with the SENSE S2 and float the device in your pool. 

With that said, you would need to ensure that the SENSE S2 in the float ring has sufficient water flow to provide accurate readings.  Some customers tether the SENSE S2 in the Float Ring to the corner of the pool near where the pool pump is pumping water.  

Only tether the device if the pool is used only by adults.  Tethering the SENSE S2 to the side of the pool might present a choking hazard if the pool is used by children of any age.
