Hello,
I wanted to measure water level up to 50 Mts with 5 cm accuracy. Can I use a pressure sensor for this purpose? I tried a pressure sensor with built in amplifier got from one supplier. I kept it at a depth of 2.5Mts of water and monitored the output throughout day time. I found a variation of 1.5% in the output voltage. What could be the reasons for such variations? Could it be due to the atmospheric pressure variation? Is there any way to compensate it?
Your help will be highly appreciated.
