• Stack Monitor

    Increase confidence of ram position due to real-time monitoring.



    We understand safety is one of your main concerns at the well site, and that real-time monitoring can help ensure your equipment and personnel continue to work at full capacity. The Texas Oil Tools™ Stack Monitor, mounted in the control cabin, increases your team’s confidence by providing real-time data of your entire stack, allowing you to monitor the blowout preventer (BOP) rams’ position, Hydraconn latch and lock systems, and stripper pressures.

    Our software allows you to determine if the rams are fully opened or closed from the control cabin. It uses calibrated values to compare against BOP ram movements to determine if full displacement is achieved, and if a ram motion is not within accepted tolerances a partial movement alarm is triggered. Additionally, the Hydraconn monitoring system senses both the latch and lock system, and the hydraulic pressure applied to the pack-off side is monitored for the stripper packer.

    Monitoring the BOP stack and the position of the rams provides a clear and concise reading for the operator and other interested parties at the well site.


    • Track each BOP ram and Hydraconn state to indicate current conditions and movement
    • Toggle between metric and imperial units and day and night screen settings
    • Get accurately scaled values based on different pressure transducers and ambient conditions
    • Feedback for wire break conditions and partial movement events by system alarms
    • Simply display all alarm statuses simultaneously
    • Manually enter configuration if indicated states differ from known conditions
