FC2W is a flow controller for water between 0-50°C.  A motor driven adjustable flow restriction works together with feedback from a Karman vortex flow sensor to respond to an analog input signal establishing the flow rate.  When a single water supply source is divided into multiple lines, the flow rate between lines can be inconsistent.  FC2W controllers can adjust flow on each line to a constant rate.  FC2W does not include a flow shutoff feature.  Pair the controller with a VXZ 2-port soleoid valve to stop flow for any reason.  The device includes an error status LED.  This is a grease-free product.
