  • Page 10: Truesense Coms And Qwest Unit Description

    The TrueSense* for Process Crude Overhead Monitoring System (COMS) and Quench Water Enhanced System Treatment (QWEST) were designed by Veolia Water Technologies to effectively measure pH from the Overhead Atmospheric Tower, and other similar processes in a Refinery or Chemical Plant, including quench water systems.
  • Page 11 COMS & QWEST Gen 3 Owners and Maintenance Manual The analyzer is prepared to receive signals from other analyzers that measure process such as Chlorides, Ammonia and Iron. The pH signal enters the air-purged electronic enclosure.
