DMC’s client is in the business of specialty and explosive gas distribution. One facility was using a manual method of filling and handling Acetylene tanks. To improve quality and safety, there was a need to implement a solution that automated the measurement and refilling process, while still allowing for necessary operator interaction.<\/p>\n\n\n\n
DMC designed and developed a system to perform this automation in a hazardous location. The HMI program guides the operator through a sequence of steps to connect a tank to the system. The system contains a scale and weight and pressure-based valuations that estimate the level of Acetone remaining and the amount needed. After measurement and refilling is complete, the system gives the operator instructions for disconnecting the tank and resetting the sequence.<\/p>\n\n\n\n
DMC provided thorough documentation for both sequence-based and operator-based interactions as well as for different tank types.<\/p>\n\n\n\n
Due to the facility’s explosive gases, hazardous rated hardware devices were used on the system. DMC designed and implemented a control panel with Z Purge to inject an inert gas into the electrical control panel to ensure safe operation.<\/p>\n\n\n\n
