FC2W, Flow Controller for Water, Pulse Output, 0.5-16 Lpm
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.
