An interior sensor system is arranged on the housing to obtain information about any fluid in the interior of the housing different than the location of the tank.
Arrangement and method for monitoring a fluid storage tank which includes a housing defining an interior receivable of a removable fluid. An interior sensor system is arranged on the housing to obtain information about any fluid in the interior of the housing different than the location of the tank. A location determining system is arranged on the housing to monitor the location of the tank, and a communication system is coupled to the interior sensor system and the location determining system and which is arranged to transmit the information about the fluid in the interior of the housing and the location of the tank to one or more remote facilities. The communication system may be arranged on the housing itself, which is especially applicable when the housing is movable, for example, such as the housing of a Frac tank. The location and condition of the fluid in the tank can thus be known at all times.

The method of claim 1, wherein the container is a movable container, the step of detecting the occurrence of the first event comprising: detecting a change in position or location of the container or a part thereof or vibration of the container or a part thereof; and obtaining the information about the material in the interior of the housing at the second instance only after the change in position or location of the container or part thereof or vibration of the container or part thereof is detected and then the container is stationary such that the information obtained at the second instance is obtained when the container is stationary. 8. The method of claim 1, further comprising fixing the housing in position to be immovable. 9. The method of claim 1, further comprising, at the remote facility, warning monitoring personnel about a problem with the material in the container or a problem with the container. 10. The method of claim 1, wherein the information is periodically transmitted to the remote facility via a communication system arranged on the housing. 11. The method of claim 1, wherein the interior sensor system comprises at least one wave transmitter/receiver, further comprising: directing waves at an upper surface of the material when present in the interior of the housing via the at least one wave transmitter/receiver; and using a processor to analyze waves received by the at least one wave transmitter/receiver and obtain information about the material in the interior of the housing based on the analysis of the waves received by the at least one wave transmitter/receiver. 12. The method of claim 11, wherein the material is a fluid and the processor is arranged to compensate for gas density gradients in the interior of the housing. 13. The method of claim 11, further comprising: arranging at least one reference target in the interior of the housing each at a known distance from the at least one transmitter/receiver and in a field of transmission of the at least one transmitter/receiver; and arranging the at least one transmitter/receiver to receive waves from the upper surface of the material and from the at least one reference target, the processor analyzing the waves and determining the level of material in the interior of the housing knowing the distance between the at least one transmitter/receiver and the at least one reference target. 14. The method of claim 11, wherein the at least one transmitter/receiver is arranged to transmit and receive ultrasonic waves. 15. The method of claim 1, wherein the interior sensor system comprises at least one wave transmitter/receiver, further comprising: directing waves from a top of the housing downward toward a bottom of the housing via the at least one wave transmitter/receiver; comparing waves received by the at least one wave transmitter/receiver at different times using the processor; and obtaining information about the material in the interior of the housing based on the comparison of the waves received by the at least one wave transmitter/receiver at different times. 16.
