A method and an apparatus for remotely and automatically monitoring for corrosion of a tank, pipe, or container with a gas or liquid environment using corrosion coupons that do not have to be removed from the environment for inspection and evaluation. The coupons are designed to fail when a specified level of corrosion occurs. A permanent magnet located on a coupon sensing system inside the corrosive environment is used to transmit the failure of the coupons outside the corrosion environment and across a wall or other boundary surface without requiring a power supply.

Method and apparatus for remotely monitoring corrosion using corrosion coupons

A method and an apparatus for measuring the pressure or other physical quantities of a gas or a liquid in a sealed container without penetrating the container. Two permanent magnets, one located on a sensing unit inside the container and one located on a readout unit located outside the container are used to communicate the magnitude of the pressure sensed inside the container to the readout unit. No power supply is required to implement this system.
