Abstract: Embodiments of the present invention relate to an attachment mechanism adapted to be attached to fluid system having a hydroelectric generator adapted to convert a flow of a fluid through the fluid system into electrical power. The attachment mechanism further includes a control unit coupled to the hydroelectric generator, capacitor to store the electrical power generated by the hydroelectric generator, and a motor coupled to the control unit. In addition, the attachment system includes a pinch valve coupled to the motor, such that the control unit is adapted to automatically control the motor for actuating the pinch valve for regulating the fluid flow within the fluid system. The attachment mechanism further includes sensor unit to detect the condition in vicinity to the attachment mechanism. As further disclosed herein, the control unit is powered by the flow of the fluid through the fluid system.
