Fluid Components International's Model ST51 mass flowmeter
Model ST51 mass flowmeter is designed as an application-specific solution for wastewater treatment digester flow measurement applications. It is designed to measure digester gas, biogas and other methane composition biofuel gases as well as natural gas. The flowmeter calibrates in its NIST-traceable flow lab to match the gas composition of the user's digester system and under the specific flow conditions of the user's digester system, which results in an instrument that is matched precisely to the facility's actual operating environment. Flow range is from 0.3 to 400 SFPS and repeatability is ±0.5% of reading.
