Model 400/470 Flo-Controller Package
Description
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.
