Is the below Dewalt cordless drill fake or the real deal? 1,390 baht for a 48V sound a bit odd, but are they really so blatantly selling brand name fakes on Lazada? https://s.lazada.co.th/s.eHWnM

I have this 36 m3 tank to capture rain water for domestic consumption. What is the best way to monitor the water level? When full, the water level is 2.25 m, so the below 4-20 mA for a 0-5 m span would kind of do the job, but is there a way to capture the data to see seasonal variations in the water level. Some sort of app or data acquisition system? https://s.lazada.co.th/s.enY4R https://s.lazada.co.th/s.eNz2a
