A device for monitoring the level or amount of a material within a container is provided. The device includes a detection mechanism that can be a direct detection mechanism or an indirect detection mechanism. When the detection mechanism senses an upper level of the substance in the container that is below a predetermined lower limit for the substance, the mechanism operates an alarm mechanism to emit an alarm to alert an individual to the low level of the substance within the container. The alarm can wirelessly communicate a salt level state to a wireless network or a device on a wireless network that can transmit the status through the Internet to any remote location. In one aspect, the alarm can be sent on a mesh network with a device that can transmit the status and other conditions through the Internet and to an application executing on a mobile device.

A float assembly comprising a float traveling along a rod until making contact with either an upper or a lower adjustable stopper, so that an actuator lever having one or more counterweights in mechanical coupling with a switch, so that the float assembly may respond to the fluid level.

A fuel level circuit for dual tank configuration includes fuel level sensors in each of two tanks and a fuel level display that can display the fuel level in one tank. The tank to be displayed on the fuel level display is selected by a flow diverting valve that selects the tank from which fuel will be delivered to a prime mover. A magnetic element moves with the flow diverting valve to actuate a magnetic switch to open or close a circuit element. A fuel selection relay places the fuel level display in communication with the fuel level sensor of the selected fuel tank in response to the magnetic switch opening and closing the circuit element.
