Description
The Carrier HR81LD001 is a Flow Switch, an essential safety part of Carrier HVAC systems, especially those that involve liquids. This compact device, with dimensions of 3.4” x 3.7” x 5.3”, measures the flow of the liquid within the system. The functions include sensing flow rate fluctuations or total flow stoppage. It is designed to support both the sequencing and the switching applications. If the flow rate drops below a specific level or if the flow stops, the switch provides a pre-set signal to the Carrier equipment. This might involve turning off the system to avoid damaging the pumps or other parts of the system, because of excessive heat.
