Abstract:
1. A method, comprising: developing, at a main regulator valve, a main line pressure having a first pressure level configured to overcome at least one anticipated variation in the main line pressure from an expected pressure level; developing, at a control main valve, a control main pressure based on the main line pressure; adjusting the main line pressure from the first pressure level toward a second pressure level configured to overcome the at least one anticipated variation in the main line pressure from the expected pressure level; determining whether the control main valve has transitioned from a regulating state to a non-regulating state; generating one or more first calibration parameters in response to determining that the control main valve has transitioned from the regulating state to the non-regulating state; adjusting the main line pressure from the second pressure level toward the first pressure level; determining whether the control main valve has transitioned from the non-regulating state to the regulating state; generating one or more second calibration parameters in response to determining that the control main valve has transitioned from the non-regulating state to the regulating state; and using the first and second calibration parameters to adjust the main line pressure.
