Boiler Temperature Gauge and Boiler Pressure Gauge

Boiler temperature gauges; Pressure may be recorded as gauge pressure or as absolute pressure. Gauge pressure is the pressure above that of the atmosphere. Absolute pressure is the pressure above zero pressure, equal to gauge pressure plus the atmospheric pressure. At sea level, atmospheric pressure is 14.7 psi. Pressure gauges
