A flow control that is configured to monitor energy use. These configurations may include a controller that delivers a signal to pressurize a pneumatic actuator. This controller may have software that can calculate energy use based on pressure of the signal and, for example, changes in position of a valve. This feature can provide real-time data that operators can use to identify potential problems on their process lines. In one implementation, the operators can flag devices that exhibit energy use that trends away from baseline levels. These devices may have inherent issues that can manifest into larger, more catastrophic problems, potentially causing quality problems with end product or requiring the operating to shut-down the process line altogether.
