The present invention affords a method and apparatus for autonomous fueling/refueling of numerous machinery operating at work sites such as an active fracking site. The system of the present invention includes a main fuel tank mounted on a frame and a plurality of fuel intake lines individually coupled to the main fuel tank. Pumps are connected to at least some, but not necessarily all, of the fuel intake lines. The pumps are coupled to hoses extending from the main fuel tank to the saddle tanks requiring fueling/refueling. The present invention further includes a refueling cap that is detachably connected to the hoses and configured to mate with the saddle tanks. This cap includes a pressure valve configured to open only in the presence of sufficient pressure input pressure from the hose, which prevents siphoning of fuel out of the saddle tank, for example if a hose becomes ruptured somewhere along its length. The refueling cap further includes a vent coupled to a fluid flow sensing valve and an electrical pass-through for a pressure sensor. The pressure sensor is coupled to the refueling cap and intended to be disposed within a saddle tank to provide a signal indicative of the fuel level within the saddle tank. The pressure sensor is further electrically connected to a wireless transmitter. The wireless transmitter provides signals to a controller for the pumps. In one methodology of the present invention fueling/refueling of individual saddle tanks is initiated when a first signal is received from the wireless transmitter indicative of the saddle tank having been depleted to a first predetermined level and fueling/refueling is terminated when a another signal is received from the wireless transmitter indicative of the saddle tank having been filled to a second predetermined level or if a signal is received from the wireless transmitter indicative of the fluid flow sensor detecting fluid flow through the vent.

A system and method for retrofitting an electric center irrigation pivot to have a standardized user interface and remote control functionality. A local control element having a standardized local user interface is installed at a pivoting point of the pivot by bypassing an existing control logic of an original control system while using an existing transformer of the original control system. A remote control element having a standardized remote user interface is also installed at the pivoting point of the pivot, and is functionally integrated with the local control element. A position-determining element is mounted on a movable portion of the electric pivot. Retrofitting multiple pivots provides each with the same standardized user interfaces. Because existing elements of the original control system are either bypassed or used, uninstalling the system and reverting to the original control system can be quickly and easily accomplished.
