    摘要: System for monitoring a floating roof of a tank containing a liquid, wherein the system determines a local status of the floating roof in spaced apart sensing element locations. In a hazardous or potentially hazardous environment, there is an on-roof subsystem including a sensing element in each sensing element location, intrinsically safe measuring circuitry coupled a sensing elements and arranged for determining said local status, intrinsically safe radio communication on-roof circuitry coupled for communicating externally of the on-roof subsystem the local, an intrinsically safe power supply circuitry connected to an intrinsically safe and interchangeable energy storage unit for powering the on-roof subsystem. The system further includes monitoring circuitry for receiving the indication of local status and for determining an overall monitored status of said floating and further radio communication circuitry. The on-roof subsystem is wireless in its power supply and communication.
