An angle of attack sensor includes a vane assembly and a multi-piece faceplate adjacent the vane assembly. The faceplate includes a mounting plate having an opening and a heated chassis positioned adjacent the mounting plate and having a ring portion extending through the opening, the ring portion defining a ring-shaped deflector that surrounds the vane assembly and extends beyond an exterior surface of the mounting plate.

An electrical control system may include a sensor unit with an attachment mechanism for mounting the sensor unit to a fluid pipe, a fluid flow sensor, and a signal generator configured to generate a signal indicating at least one of whether the flow sensor detects a fluid flow in the fluid pipe or whether the flow sensor detects no fluid flow in the fluid pipe. The system may also include a control unit having one or more of an electrical plug, an electrical socket, an interruptible circuit between the electrical plug and the electrical socket, a receiving device configured to receive the signal from the sensor unit, and a processor configured to interrupt the circuit between the electrical plug and the electrical socket based on at least one of receipt of the signal or interruption of the signal.

The water conduit flow indicator is a device that is configured to be installed between a spigot and a water conduit in order to provide an audible alarm that water fluid is flowing through the device. The water conduit flow indicator is further defined with a housing that features an inlet and an outlet. The housing includes an internal partition that separates a fluid side from a dry side. Located within the housing is a pair of impeller blades. The pair of impeller blades is further defined with a fluid impeller blade and a dry impeller blade. The dry side of the housing includes a ringer bell that comes into contact with the dry impeller blade such that as the dry impeller blade rotates, the ringer bell generates an audible noise that alerts an end user as to the fluid flow occurring through the water conduit flow indicator.
