ELECTRONIC VALVE POSITION INDICATOR

摘要

An apparatus includes a valve having at least two input ports. A first of the at least two input ports connected to a first source of material and a second of the at least two input ports connected to a second source of material. The also valve includes an output port and a valve selector for selectively connecting one of the at least two input ports to the output port. An electric circuit selectively connects an output device to receive data from a first sensor associated with the first source of material that senses at least one characteristic associated with the first source of material when the valve selector is in a first position connecting the first of the two input ports to the output port, and a second sensor associated with a second source of material that senses at least one characteristic associated with the second source of material when the valve selector is in a second position connecting the second of the two input ports to the output port.
