I am looking to fit a sensor to a plastic tank, in this case water
I am keen to avoid cutting holes and other invasive operations.
I am already discounting the use of internal floats and sight tubes or even sticks!
Has anyone retrofitted a external, maybe an ultra sonic gauge with successful results?
A few years ago a similar thread ran and Scad systems were recommended- is this still best of breed.
Remember no sticks, tubes or floats please!
