Monitoring Water Level in a Tank

Former Member

I wan to automate a test that I conduct frequently.  I want to record the drop in water level in a water tank over 30 minutes then trigger a valve with solenoid (able to operate by gravity flow, no pressured water) to refill the water back to same level and then wait another 30 minutes.  Each time interval will have a set of data representing the water level in the tank.  I was told I need a microcontroller, an e-tape (from Milone technologies) and a water valve.  Can anyone help in pointing out what instruments are needed and how to connect them.  I was told that I don't need a data logger if the controller can control a valve and log data.  If someone an help , I will draw a sketch if needed. Regards

    cool.  do you know how to hook it up to a controller so it can open the water valve and close it when water level reaches the full depth and then monitor the water drops and record the data (time vs depth) for 30 minutes.  then open valve again until water reaches full level, stop the valve and let the water drops again.  My issue is not knowing the programing part.  I bought almost everything mentioned in the above emails, but need direction to move forward.  I will buy this item. if you can take a stab at the programing.  Controller/logger, sensor, valve.  If you know someone who is willing to take the time to work on it.  I tried to have Doug (see the thread above) help out, but he may be busy.
