1. Understanding Rae RAC Flow Switches
Rae RAC flow switches are thermal dispersion flow switches designed to monitor flow rates in pipes and ducts. They are utilized in a wide range of applications, including pump protection, HVAC systems, and industrial process control. These switches operate based on the principle of heat transfer: a heated sensor is cooled by the fluid flow, and the temperature difference is used to determine the flow rate.
1.1 What are Rae RAC Flow Switches?
Rae RAC flow switches are devices used to detect and monitor the flow of liquids or gases in a pipeline or system. They are known for their reliability and ease of installation. These switches are often used to protect pumps from running dry or to ensure adequate flow in cooling systems.
1.2 How Do Rae RAC Flow Switches Work?
Rae RAC flow switches utilize thermal dispersion technology. A heated sensor monitors the temperature differential caused by fluid flow. When flow decreases or stops, the heated sensor’s temperature increases, triggering a switch. This switch can then be used to activate an alarm, shut down a pump, or perform other control actions.
