The Emerson Flow Control (Alco) 048816 Moister Liquid Indicator is an essential component of HVAC systems, which is used to determine the presence of moisture in the refrigerant lines visually. This small-sized with 1-1/8” Sweat X Sweat OD Female connections has a sight glass to enable the user to monitor the flow of the refrigerant. This is because when there is moisture it forms droplets or a foggy appearance in the sight glass when it is inside the system. This visual indication is an early warning sign of system issues that may include, leaks, oil contamination or improper system charging.
