Abstract
A floating roof monitoring system is disclosed. According to embodiments, the floating roof monitoring system includes a monitoring device and a floating roof tank. The monitoring device can generate a current for a monitoring loop that includes one or more electrical connections between the monitoring device and the floating roof tank. A resistance value for one or more points within or along the monitoring loop can be determined and monitored. The monitoring device can determine, based upon the resistance value, if an action is to be taken.
Claims20
A floating roof monitoring system comprising:
- a floating roof tank comprising a floating roof and a shell, the floating roof tank being conductively connected to a grounding device;
- and
- a monitoring device conductively connected to the grounding device and the floating roof tank, the monitoring device being configured to:
- generate a current for a monitoring loop comprising electrical connections between the monitoring device, the floating roof tank, and the grounding device;
- monitor a resistance value associated with the floating roof tank;
- and
- determine if a remedial action is to be taken based, at least partially, upon the resistance value.
A method for monitoring a floating roof tank, the method comprising:
- generating, at a monitoring device, a current for a monitoring loop comprising electrical connections between the monitoring device, a floating roof tank comprising a floating roof and a shell, and a grounding device;
- monitoring a resistance value associated with the floating roof tank, the resistance value being determined for at least one point along the monitoring loop;
- and
- determining if an action is to be taken based, at least partially, upon the resistance value.
A method for monitoring a floating roof tank, the method comprising:
- generating, at a monitoring device, an intrinsically safe current for a monitoring loop, the monitoring loop comprising electrical connections between the monitoring device and a remote input/output device, between the remote input/output device and a floating roof tank comprising a floating roof and a shell, and between the remote input/output device and a grounding device electrically connected to the floating roof tank;
- determining an expected resistance value associated with the floating roof tank, the expected resistance value corresponding to a resistance expected for at least one point along the monitoring loop;
- monitoring a measured resistance value associated with the floating roof tank, the measured resistance value being obtained for the at least one point along the monitoring loop;
- determining a difference between the measured resistance value and the expected resistance value;
- comparing the difference determined with a threshold difference value;
- determining if the threshold difference value is satisfied by the difference determined;
- and
- taking an action based, at least partially, upon determining that the threshold difference value is satisfied.
