Hi all. I’m looking for a cheap way to measure water level data in sand dams over an extended period of time to monitor functionality. I want it to be pretty automated. I found the "heron logger" which costs about £335. And that’s not including the actual installation costs (the distributor puts the total installation cost at over £1500, which is way above budget though I’m sure it can be done cheaper)
I was wondering if anyone knows a cheap alternative solution. I really don’t need great accuracy. Even logging at three heights in the dam would be fantastic.
A friend sent this fantastic article about modifying other loggers to make a presence absence logger but I need at least 2 heights and I thought I would check my options before attempting it. http://onlinelibrary.wiley.com/doi/10...
I was thinking of just putting a tube into the sand and getting someone with a string and a float to check it but it seems undesirable to the org.
Again great accuracy is not essential.
Thanks for your advice.
