R79704: Caleffi Liquid Flow Indicator with Visual Alarm The Caleffi R79704 is a liquid flow indicator with a visual alarm, designed for use in residential and commercial hydronic heating and cooling systems. It features a transparent body that allows for easy visual inspection of the fluid flow, and a built-in alarm that triggers when the flow rate drops below a predetermined level. The R79704 is constructed of durable brass and has a maximum operating pressure of 10 bar. It is suitable for use with water, glycol solutions, and other non-corrosive fluids. The visual alarm is activated by a magnetic float that rises and falls with the fluid flow. When the flow rate drops below the set point, the float drops and triggers the alarm, which is indicated by a red indicator flag. The R79704 is a valuable tool for monitoring the flow of fluids in hydronic systems. It helps ensure that the system is operating properly and that there are no blockages or other issues that could affect the performance of the system.
