I would like to come up with a system to display liquid level inside a container, I doesnt have to be very accurate as is quite large at 2600 litres (about 570 gallons)
I basically just need about 10 levels of measurement, with a low level warning, which itself doesnt seem too bad.
The only other thing is I would like it to also have a rate of change warning, so if it dropped by more than 1 level in for example 1 hour, it would also trigger an alarm.
I am thinking of going for somthing ultra-sonic, but have not had an previous experience using them, so dont really know where to start.
Can anyone point me in the right direction of sites that may have any plans for using ultrasonics for liquid measurement to use as a starting point.
Any help is greatly appreciated.
