 the nozzles must water a large annular ring around the sprinkler which results in watering that is not uniform across the annular ring (i.e., in a radial direction from the nozzle). As a result, these conventional sprinklers waste water and are inflexible to landscape variations.
Irrigation systems have been disclosed that comprise, for example, a computer server with one or more wireless networks, one or more computerized sprinklers with a digitally controlled valve connected by wire to the server, one or more controllers with Wi-Fi plus another wireless network and one or more flow sensors connected by wire to the controller. Exemplary irrigation systems are disclosed in International Patent Application Serial No. PCT/US2011/044337, filed Jul. 18, 2011, and U.S. patent application Ser. No. 13/744,588, filed Jan. 18, 2013. The above referenced patent applications are incorporated herein by reference in their entirety. In these irrigation systems, each sprinkler provides a uniform incremental amount of precipitation to the soil for each revolution and can also adjust the incremental amount for a given arc portion of a revolution. In one embodiment the server and controller are combined and in another embodiment they are separate thereby creating more flexibility.
The systems must be properly calibrated to provide the desired watering pattern including the throw distance the watering stream travels from the sprinkler head over various arc portions of a revolution. Furthermore, it has been determined that a consistent pressure and flow are desirable to maintain efficiency where efficiency is defined by the system using the desired amount of water. Too much pressure causes too much flow resulting in over-watering and a throw distance that is too long, and too little pressure causes too little flow resulting in under-watering and a throw distance that is too short.
An installation contractor may use a pressure gauge to measure static pressure, but that does not account for working pressure loss under flow conditions in pipes and fittings in the field. The contractor can also turn on the sprinkler and measure the distance of the streams which are reflective of the flow conditions under working pressure, but this has proven to be complicated and slows down the installation. There is a need for automatically finding the effective pressure for a particular irrigation sprinkler and setting the sprinkler distance at a particular installation site. The temperature of a charging battery is a critical factor in the proper control and the ultimate safety of equipment and personnel in the charging process. If the temperature of the battery increases significantly, the internal resistance
the nozzles must water a large annular ring around the sprinkler which results in lacrimation that is not consistent across the annular ring (i.e., in a radial direction from the beak). As a result, these ceremonious sprinklers waste body of water and are inflexible to landscape variations. 
 Irrigation organization have been disclosed that comprise, for example, a calculator server with one or more wireless networks, one or more computerized sprinklers with a digitally controlled valve connect by wire to the server, one or more controllers with Wi - Fi plus another wireless network and one or more flow detector connected by wire to the controller. admonitory irrigation systems are disclosed in International Patent Application Serial No. PCT / US2011/044337, file Jul. 18, 2011, and U.S. patent application Ser. nobelium. 13/744,588, filed Jan. 18, 2013. The above reference patent applications are incorporated herein by reference in their entirety. In these irrigation systems, each sprinkler provide a uniform incremental amount of precipitation to the soil for each revolution and can besides align the incremental sum for a given arc portion of a revolution. In one embodiment the server and control are unite and in another embodiment they are separate thereby create more tractability. 
 The systems must be properly calibrated to provide the desired watering pattern including the throw distance the lacrimation stream travels from the sprinkler head over various arc portions of a revolution. Furthermore, it has been determined that a consistent pressure and flow are desirable to maintain efficiency where efficiency is define by the arrangement using the desired amount of water. Too much atmospheric pressure causes too much flow result in over - watering and a throw distance that is too long, and besides little imperativeness causes too small flow result in under - watering and a throw distance that is excessively short. 
 An initiation contractor may use a pressure gauge to measure electrostatic pressure, but that does not account for working pressure loss under flow conditions in pipes and fittings in the battlefield. The contractor can also sour on the sprinkler and measure the distance of the streams which are brooding of the flow conditions under working pressure, but this has proven to be complicated and slows down the installation. There is a need for automatically finding the effective press for a especial irrigation sprinkler and specify the sprinkler distance at a particular installation web site.
