Model 1100 in-line flow sensor uses a magnet-equipped shuttle that displaces at the proper calibrated flow of liquid to actuate a SPDT hermetically sealed reed switch within the stem. Factory ...

A sensor measures flow for the Arduino, which adjusts a control valve actuator to maintain the specified setpoint. The software uses proportional and integral control (the PI part of a PID loop).
