Pressure Gauges are an essential item for drip systems since visual monitoring is often impractical or impossible. Pressure gauges placed at the pump station, before and after the filter station, and upstream and downstream of each control valve will provide an immediate indication of system performance. If pressures are too low, a leak could be indicated, a filter plugged or a valve jammed. If pressure are too high, the system could be plugged or a valve may be set incorrectly. Similar to a flow meter, accurate pressure information is essential part of a well designed and operated drip system.
