These gauges are designed to be set up in a head to head or grid pattern to determine how much water is applied from an irrigation system and to also show the water coverage uniformity. They are also useful in performing water audits with companion tools like Infiltrometers and moisture sensors. The set of 20 gauges are calibrated in tenths of an inch and millimeters for ease of reading the amount of water in each gauge. The measuring cups are made from strong plastic and the mounting brackets are made from stainless steel for ease of use and long life. The set consists of 16 large gauges and 4 small gauges. The small gauges are positioned closest to the sprinklers to insure water collection from second and third stream nozzle designs.
