Description
The Dwyer Instruments V4-2-U-MT Flotect Vane-Operated Flow Switch V4 is a mechanical flow-sensing component used in determining fluid is flowing in HVAC systems. It is fitted to compatible hydronic or chilled water lines, and the internal vane swings with the flow of fluids to open a switch contact. It is placed in the middle of the HVAC systems, where it is linked to the control circuitry to indicate the flow status. In the assembly, the control system, can confirm that circulation is present in the process of heating or cooling.
