Hi,
I'm developing an ultrasonic sensor to measure the depth of the sludge in large tanks. But for now i'm trying to measure water depth. My transducer is the TD40200D, it's recommended 1000vpp supply but it should works fine with 300vpp for my needs.
I have no ideia how to start it, does anyone have experience in this area ? I was thinking about doing reverse engineering in one fish finder, What do you think?
Best regards,
Alexandre Becker

These are typical depth indicators, 200Khz transducer freq. this one is a digital read out. This should give you some ideas.DIG SOUNDER.1.jpgDIG SOUNDER.2.jpgDIG SOUNDER.3.jpgDIG SOUNDER.4.jpgDIG SOUNDER.5.jpgDIG SOUNDER.6.jpgDIG SOUNDER.7.jpgDIG SOUNDER.8.jpg
