Hi All,
I am currently busy with a home project using a water backup and storage system. I have 3 x 2050 liter x 1.85 meter high by 1.45m in diameter tanks interconnected. I would like to use an accurate non-expensive method to measure the amount of litres in the tanks. Can anyone give me some pointers please. I would also like to measure the amount of water consumed as well.
Any suggestions would be welcome.
Thank you

Hi.
I think the easiest way is to use an ultrasonic sensor to measure the distance from the top of the tank to the level of the water.
Then, accordingly to the shape of the tank, you can calculate the volume of water.
I haven’t tried this method, so I’m not sure how accurate this is…
Regards,
Sara

As Sara has said, use one of the waterproof ultrasonic sensors. You could also opt for using a pressure transducer. As your tanks are interconnected, you will need to sum up their volumes to represent 100%. For flow, your best is to fit a digital flow meter (paddle wheel type) to the main outlet of your tanks.

Andrew

I did some research and found the following sensors: A02YYUW and JSN-SR047
These are both Waterproof distance sensors. The JSN-SR047 has a 300mm blind spot where the A02YYUW has 3cm blind spot according documentation and some videos I watched,
The A02YYUW will be the chosen sensor.
The calculations are not difficult. I can work with this.
Thanks for the input.
Kind regards
