The ST51A and ST75A thermal mass flowmeters are designed for air/gas flow measurement and other process applications. The Model ST51A flowmeter is an insertion-style instrument designed for use in pipe diameters larger than 2 inches (51 mm). The ST51A meter is optimized for flow measurement of air, compressed air, nitrogen, natural gas, digester gas and all other biogases. The ST75A flowmeter is an inline-style instrument designed for use in pipe diameters from 0.25- to 2-in. (6 to 51 mm). The ST75A meter is designed for applications in air, all inert gases, natural gas and other hydrocarbon gases. Both models feature wide 100:1 turndown, have no moving parts, IP67 dust/water ingress protection and rugged, all metal enclosures.
