  • Publication number: 20190054488
    Abstract: An irrigation sprinkler can be provided with a flow guard feature configured to send an indicator stream into the air when a nozzle is missing, while still conserving most of the water that would have been wasted without the flow guard feature. The flow guard feature can include a valve assembly having a first port and a second off-axis port. The second port can be smaller than the first port. The second port can be non-parallel to the first port. The first port can be open when the nozzle is present and be sealed when the nozzle is missing. The second, off-axis port can be open even when the nozzle is missing to provide the indicator stream.

  • Patent number: 9808813
    Abstract: A sprinkler nozzle includes a nozzle plate having at least one orifice formed therein. A stream deflector is rotatably mounted adjacent the nozzle plate and has a plurality of flutes formed therein that face the nozzle plate. Each flute has an inner portion that can momentarily align with water flowing through the orifice in the nozzle plate during rotation of the stream deflector relative to the nozzle plate. Water flowing through the orifice will be channeled in a generally radial direction by the flute to form a stream of water that is ejected from the stream deflector. The flutes have a plurality of different tangential trajectories relative to the orifice in the nozzle plate so that in combination the streams of water successively ejected from the stream deflector establish a predetermined shape of coverage.

  • Patent number: 9662668
    Abstract: An irrigation sprinkler can include a riser and a nozzle mounted at an upper end of the riser for rotation. The sprinkler can include a high flow rate port and a low flow rate port that can each emit a stream of water.

  • Patent number: 8793024
    Abstract: An irrigation controller has a control panel including a display and a plurality of user inputs. A processor is operatively connected to the control panel and to a memory. A plurality of switches are operatively connected to the processor for turning a power signal ON and OFF to a plurality of valves that deliver water to a plurality of sprinklers in different zones. Programming is stored in the memory for implementing a seasonal adjustment feature that is independently operable with a plurality of individual watering programs to selectively energize the valves. The programming calculates a soil moisture requirement value for each program using a signal from at least one soil moisture sensor that is associated with a zone that is assigned to that watering program, and automatically modifies the watering program assigned to that zone through the seasonal adjust feature based on the soil moisture requirement value.

  • Patent number: 8301309
    Abstract: An evapotranspiration (ET) unit includes a processor and a memory for storing a historical set of components of ET data. The processor can communicate with one or more environmental sensors each capable of generating a signal representing an actual value to be substituted for a corresponding one of the components of the historical set. Preprogrammed algorithms enable the processor to calculate changes to a set of watering schedules of a predetermined watering program of an irrigation controller based on any substituted actual value and the remaining historical set of components. The ET unit 10 communicates the changes to the irrigation controller.
