Digester Biogas Flow Monitoring

A wastewater treatment plant needed to measure biogas traveling into and out of a gas line leading into a Digester Dystor gas bag. The amount of gas and direction of flow is critical for measurements to meet EPA regulations. 

The station receives the information via the primary programmable logic controller (PLC) that communicates back to the Distributive Control System (DCS) with a Dystor quantity value. A real-time running calculation of gas quality contained within the Dystor is calculated at primary and secondary PLC's.
