Monitoring pressure relief events helps operators gain additional visibility into their process, while adhering to incrementally important environmental standards. Undetected pressure relief events can lead to issues relating to safety, emissions, reliability, and productivity. Pressure relief valves have historically been “off-grid”, but changes in environmental regulations, in conjunction with an increased interest in efficiency and productivity are driving the need to monitor pressure relief events.
Emerson’s solution for Anderson Greenwood high-pressure and low-pressure pilot valves includes the choice of a Rosemount 3051 or 2051 differential pressure transmitter to monitor the differential pressure between the pressure pickup port and the main valve dome. The differential pressure between these two points has a direct correlation to the valve lift percentage. This featured, paired with an Anderson Greenwood modulating style pilot valve, is the most accurate way to monitor, record, and report the volumetric flow during a pressure relief event.
