My nephew, who is a field engineer, tried to explain something to me about fuel tank monitors and alarms. And there are these gauges that monitor allowable space and also pick up changes of viscosity and vapors, that might lead to an overflow situation. And he said that sometimes they are too sensitive, and the alarms go off if there is an internal shift or change picked up by the gauges. So he said that he might not have wanted to add both bodies, although they were very small, just because the alarm system might be triggered if there was odd movements or shifts or changes inside the tank.
It kind of makes sense to me, but ?
He said that even though the body weights were very small, it is still a foreign body inside the oil tank , and sometimes the alarms pick up on changes ...
Floating Roof Tank High Level Alarm
Delta Controls Model 715-48Z
Specifically engineered for floating roof storage tanks, the Model 715 with ’48Z’ lead weight configuration offers a safe, non-invasive, and reliable level solution for storage terminals of crude oil and other materials. Utilizing a lead weight instead of a float or displacer, the roof tank lifts the weight as the level rises, triggering an alarm switch warning operators of the potential overflow. The Model 715-48Z is easily positioned above storage tanks by NPT or flanged process connections, and offers an adjustable position of lead weight along the cable. The durable design has been tested for over four decades and remains the trusted level switch for floating roof tank high level detection.
