Record Pressure Spikes in Fire Protection Systems

The AGF SMARTGAUGE Model 7550 is a 4" pressure gauge with a drag pointer designed to record system pressure spikes caused by municipal water supplies or pumps that are not working properly. The Model 7550 can be installed on a wet system temporarily or permanently to record pressure spikes so pressure relief valves can be sized correctly.

On dry systems the Model 7550 can be used to confirm municipal water supply pressures so dry valves will not be overpowered by system wide pressure increases during periods of low demand.

The SMARTGAUGE Model 7550 is a valuable addition to Hydrostatic Test Assemblies because of its ability to record the highest pressure during system testing.
