About Differential Pressure Gauges
Differential pressure gauges provide a measurement of the difference between two separate pressure points, such as within and HVAC system (such as before/after filtration, etc.). Industrial applications include those areas of process concerning flow (such as measuring process flow inside a pipe), level (to measure the difference in gas pressure from the total pressure, such as in sealed tanks) or filtration (to determine, for example, if a filter is clogged). For more on pressure control, see our flow control valves and valve accessories.
