an ultra low volume pressure independent spray head is disclosed whereby low flow characteristics of point source devices can be applied to larger wetted areas . device uses elastomeric flow control where the emission channel is large enough to purge particulate matter from it &# 39 ; s channels and the spray head has large enough orifices to allow the particulate to pass unimpeded through the discharge arena . this device is designed to utilize flow rates of less than 2 gallons per hour and can compensate for pressures between 10 and 60 pounds per square inch . construction of this device is through the use of polymers , but other materials can be used as the design is such as to allow for a large variety of applications . this device can be used in the agricultural or horticultural application and is adapted for use in vineyards and can be used singularly or in multiple head arrangements . design of inlet portion allows for use with flexible or rigid water supply means .
