Digester Biogas Flow Measurement By Steven Craig, Fluid Components International
The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system.
The RMC621 is a multifunctional flow and energy computer. It calculates standard and volumetric flow, mass flow, and energy (heat) flow using input signals of flow, differential pressure, pressure, temperature, and density.
Cadmium has many industrial uses and is predominantly used in rechargeable batteries, in yellow and red pigments, and is widely used in the aircraft industry's electroplating applications due to the excellent resistance to corrosion for cadmium-plated steel components.
