The KOBOLD Model DF-WM paddle-wheel flow switch is designed for use primarily as a flow monitor, with the additional ability to occasionally meter flow rate. The DF-WM flow switch uses a paddle wheel to measure flow. Also incorporated in the DF-WM paddle-wheel flow switch is a flow setpoint function (with relay), which can be set by the user to any value within the specified flow range. Through the use of the setpoint adjustment knob, its accompanying scale and a momentary switch (the red button), flow rate may also be approximately determined. This last function is intended only for occasional use. Like all KOBOLD DF Series flow sensors and controls, the Model DF-WM paddle-wheel flow switch is available in seven different material combinations for use with a variety of low-viscosity liquids and aggressive chemicals.
