The ST100 Series thermal flowmeter provides precision mass flow measurement. With its no moving parts, simple insertion-style design, and comprehensive, global HazEx approvals, it is a suitable solution for digester gas flow measurement. The flowmeter can be calibrated for the specific digester gas mix composition and processes temperature conditions in flow ranges from 0.25 to 1,000 sq ft per second (0.07 to 305 nanometer per second), and with accuracy to ±0.75% of reading and ±0.5% of full scale.
