摘要： An apparatus for monitoring corrosion in a pressurized system such as a water-based fire protection system comprising a corrosion monitor mounted within a section of the system containing fluid, wherein the corrosion monitor comprises a surface comprising at least one point of weakness wherein corrosion of a point of weakness causes a change in pressure in an interior chamber of the monitor, which change can be to provide a signal alerting monitoring personnel.

摘要： Systems and methods for the remote testing of a paddle-type flow detector, such as are common in fire protection systems. Specifically, the systems and methods provide for mechanical movement of the vane to test activation of the flow detector under a flow condition, and which measure the amount of time the vane takes to return to the ready position to verify the presence of a paddle on the vane.
