so.. maintenance guy and myself sit down to figure out how to measure the fluid level in a double walled tank of Sodium Hydroxide, without having to buy a $4k scale or $3k doppler reader... you cannot touch the stuff with any aluminum, or allow it to be in a sight-tube outside the tank - its an extremely potent chemical that can and will eat through things. #boom it hit me- #magnets! one in a chem-resistant tube that floats in the material. a wire outside the tank with a metal washer that slides up and down via the internal magnets attraction. - cost? under $50 I just high-fived my brain
