Process Control and Instrumentation

We have developed and implemented Process Control and Instrumentation Systems for water and wastewater clients including treatment plants, pump stations, collection systems and water distribution systems.

Our experience includes distributed control and monitoring systems for plant processes, Pump Station monitoring and control systems, and distribution and collection system monitoring and control systems that utilize Ethernet, fiber optic, Devicenet and ModBus communications.

We designed a process SCADA system for monitoring and control of five (5) indirect thin film dryers and associated thermal fluid heating systems, vapor condensate systems, sludge storage and pumping systems, materials handling conveyors, alkaline material feed systems, and odor control and treatment systems.

We developed a system wide PC-based SCADA system for monitoring and recording of thirty-five (35) separate sewage pump stations across a 40-square mile service area.

The system functions across a hybrid communications network across radio, cellular and hard-wired pathways within several communications groups.

Each group consists of multiple edge PLCs communicating to a hub PLC for data transfer to the central monitoring station.

The edge/hub arrangement allows for a Store and forward approach to data transfer to maximum data transfer reliability even during lost signals.

The system includes a triple-redundant PC Computer servers utilizing a portable laptop for mobile monitoring and recording in the event of emergency conditions at the central monitoring locations.

We understand the varying needs for data collection, information management, process controls and communications, and are prepared to assist our clients with applications that best fit their needs.
