Limescale in Ballast tank sensors

[ceac]

Hello,

I am working on a ship where we're having several failures of our level sensors (pressure sensors) due to limescale deposits.

Does anyone here know how to avoid limescale deposits on these things or which product would be advisable to use for regular cleaning of these sensors?

Are you sure that it is lime? Does it easily dissolve in dilute acid?
I am concerned that it might be a sulfide scale.
It is probably because you have mixed waters, perhaps some seawater with some high TDS well water.

There are scale inhibitors that you can add, but what about ballast discharge rules?
There are also issues with making sure that the treatments are compatible with the ship and sensors.
