How The PULSATOR Works
The PULSATOR, manufactured by Wade Rain, has an accumulation chamber which receives water through its flow controlled inlet. When the PULSATOR is full, it accurately releases the water, under pressure, which is then expelled through the spray head. The PULSATOR continuously refills and repeats the discharge many times a minute, fully covering the entire cane row. As the temperature drops, ice begins to form and soon the budwood is fully encased in a protective ice covering.

A constant flow into the PULSATOR is provided by the flow control located in the base of the unit.	As the flow enters the PULSATOR, the diaphragm expands, resulting in a pressurized condition.	The diapgragm continues to expand until the discharge seal opens, releasing a full burst of pressurized water to the jet. This represents one cycle of pulsed flow.	Following release, the diaphragm retracts and reseals the chamber. The diaphragm refills and the process repeats for the next pulse.
