The ST-326 tanker loading computer is a preset system especially designed for the automation of loading applications, whether in Safe or Hazardous areas. The ST-326 is a complete “stand-alone” control system with full communication options to link with high-end computer systems. The analog actuator control output is used to precisely regulate valve closure during an eight stage ramp-down cycle. With the mechanic SPST relays, pumps and non-drip valves can be controlled or two-stage process control of the valve.

The process is continuously monitored with functions including: earth connection, overfill alarm and flow rate monitoring. Deviations are immediately corrected or alarmed. Design flexibility permits custom-madesolutions for many applications
