Mass flowmeters

The ST series flowmeter is designed for rugged environments typically found in the oil/gas, chemical, electric power, pulp/paper and wastewater treatment industries and applications. Its no moving parts, non-clogging flow sensing element provides direct mass flow output and features built-in temperature compensation. It is suitable for use in a wide range of process and plant gas applications, including compressed air, hydrocarbon gases and inert gases. The ST98 flowmeter has a reliable thermal mass flow sensor in a smart electronics package. It operates over a wide flow range from 0.21 to 172 NMPS in air with a standard flow accuracy of ±1% of reading, ±0.5% of full scale. It is suitable for a wide range of air/gas flow measurement applications, including natural gas or methane monitoring, compressed air metering, industrial HVAC systems, nitrogen blanketing and combustion air.

The ST75 flowmeter is an accurate, direct mass flowmeter for air or gas measurement applications in smaller line sizes from 6 to 51 mm. The ST75's flow range spans 0.07 to 1425 NCMH in air, with an accuracy of ±2% of reading, ±0.5% of full scale. It is suitable for service in a wide range of industrial processes, including burner and boiler fuel/air feed lines, industrial furnaces, heat treating gas controls, chiller air flow and dosing/gas injection rate controls.

The ST50 is an insertion-style mass flowmeter for air, compressed air or nitrogen flow measurements. Designed for line sizes from 51 to 610 mm, it installs easily through a single tap point and configuration set-up takes only minutes. It operates over a flow range of 0.23 to 122 MPS in air, with an accuracy of ±2% of reading, ±0.5% of full scale. With its highly reliable thermal dispersion mass flow sensing element, the meter is suitable for a wide range of applications, including wastewater treatment, aeration applications, energy audits and efficiency of compressed air systems, nitrogen flow, HVAC duct/damper control and more.
