Using Wireless Throttling Valves in Column Control

At Emerson Exchange 2014 I worked with Stephen Briggs, University Of Texas, Austin and Kurtis Jensen, Emerson Process Management, to co-host a workshop on control using a wireless throttling valve. As addressed in this presentation, we have tested in a flow lab the control performance that may be achieved using PIDPlus with a wireless throttling …

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 …

Utilizing Wireless Throttling Valves in Control

Rev_PID vs PIDPlus in Control Using Wireless Valve

Over the last five years a wide variety of WirelessHART transmitters have been introduced by the major manufacturers of field devices. The PIDPlus enables closed loop control using the slower update rate provided by a wireless transmitter. The broad acceptance of wireless transmitters has generated an interest in the application of wireless throttling valves in …
