• Model: 7550

The AGF Model 7550 SMARTGAUGE is a 4" pressure gauge with an integral drag pointer designed to record system pressure spikes caused by Municipal Water Supplies or pumps that are not operating correctly. The Model 7550 can be installed temporarily or permanently to record wet system 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 Model 7550 is also a valuable addition to Hydrostatic Test Assemblies because of its ability to record the highest pressure during system testing.

The AGF Model 7550 SMARTGAUGE is factory calibrated prior to shipping and is marked with the date of calibration to assure the highest level of accuracy. Regularly scheduled certification is recommended. Gauges can be returned to AGF for certification, the recommended schedule is determined by frequency of use (certification is recommended every 1 to 5 years, depending on use).
