Flow rate Controller 8032

2.1 design
The flow rate controller 8032 is made up of an electronic module SE32
and a fitting S030 with integrated paddle-wheel. It may switch a solenoid
SE32
valve, activate an alarm or establish a control loop.
The switching point can be adjusted by means of the three keys located
under the display. The adjustment can optionally be carried out by means
of a 4-20 mA loop via an external controller.
S030
The electrical connection is carried out via an EN175301-803 connector
and/or a steerable M12 multipin connector.
2.2 measuring principle
The controller 8032 detects the rotation of the paddle-wheel S030. The
latter produces pulses whose frequency is proportional to the flow rate
(f = K.Q, where f is the frequency in Hz, K the K factor specific to each
fitting in pulses/l and Q the flow rate in l/s).
