We produce these sensors:
http://mechatronics.by/en/products/leve … ens-dizzi/
they can measure water easily
only demand - there is no layer of "sand" at tank bottom.
Also we made some projects with common capacitive level sensors
http://mechatronics.by/en/products/leve … inator-rs/
but with special isolated electrodes for water measurements in tanks.
only disadvantage - if somebody will damage isolation cover of electrodes - sensor will stop working.
