Classification: CPC G  H | IPC G  H

Claim 2:
3. A monitoring apparatus, comprising:
a rigid structure configured to be mounted on or in the ground;
at least one sensor externally mounted on the rigid structure and configured to detect a level of liquid in a vicinity of the rigid structure;
a housing supported by the rigid structure;
a transmitter within the housing; and
a controller within the housing, wherein the controller is in electrical communication with the at least one sensor and the transmitter, wherein the controller is configured to determine a rate at which the liquid level is changing if the liquid level is rising, and to determine a rate at which the liquid level is changing if the liquid level is falling, wherein the controller is configured to cause the transmitter to transmit rate of change data and data received from the at least one sensor to a remote device, and wherein the controller is configured to cause the transmitter to transmit a first command to electrical equipment adjacent the rigid structure to de-energize when the liquid level is rising, and to cause the transmitter to transmit a second command to the electrical equipment to re-energize when the liquid level is falling.
