The Model 400 is a liquid flow controller designed for water and other non-corrosive
fluids. It incorporates a stepper motor-actuated needle valve, a precision liquid
Flo-Sensor, and electronics that compare the output of the Flo-Sensor to the setpoint and
move the needle accordingly. The Model 470 control unit is a user interface for the Model
400. It provides a digital display, adjustable setpoint potentiometer, and power supply
for the Flo-Controller. Using optional cables (below), the user may also remotely send and
receive 0-5VDC signals to the Model 400 through the Model 470. A set of switches on the
Model 470 allow the user to select display settings and whether to use the internal or
external setpoint. Valve unit, control unit, and power adapter are included with
package. For OEM applications, the Model 400 is available by itself. Call for
