The Automated Meter Reader (AMR) Retrofit Module setup is a dynamic flow simulation kit comprising a DC motor, motor control unit, analog signal, connector and sensor connector kit. The flow is simulated as the motor rotates the shaft in forward and reverse direction. The sensor coils on board detect the circular motion of a metal disc connected to the shaft. The sensibility of rotational metal detection can be configured by changing the phase between reference excitation signal and sensor excitation signals. This sensibility is controlled by adding delay in excitation signals (in nano-second). Positive values will delay the reference excitation and negative values will delay the sensor’s excitation.
