Wireless Throttling Valve Power Consumption

Control to Minimize Changes in Target Valve Position

Something that all manufactures of wireless throttling valves must be concerned with in their design is battery power consumption. In a control application using a wireless throttling valve much of the power available to the actuator is used to track changes in target valve position. To minimize battery power consumption, the number of changes made …
