Patent ID: 7574911

Claim:
Apparatus for remote inspection of portable tanks, said apparatus comprising: a portable tank defining a volume; a gauge being disposed in communication with the volume defined by the portable tank for detection and display of pressure condition of the content contained within the volume defined by the portable tank, wherein said gauge comprises a gauge pointer and a gauge scale, said gauge pointer being moveable relative to said gauge scale for indication of pressure, and said gauge further comprises a magnet mounted to said gauge pointer and at least one sensor responsive to proximity of said magnet as the portable tank approaches an out-of-range pressure condition; and an electronic circuit disposed in communication with the gauge and adapted to signal to a remote central station upon detection of predetermined conditions comprising at least one predetermined internal condition, the at least one predetermined internal condition comprising an out-of-range pressure condition of contents contained within the volume of the portable tank, and said apparatus comprising at least one detector for the at least one predetermined internal condition comprising said gauge for detecting the out-of-range pressure condition of content contained within the volume of the portable tank.
