Thermal Mass Flow Meters & Controllers

Thermal mass flow meters measure gas mass flow from the heat carried away from a heated sensor, without separate pressure and temperature compensation. Seven Star LLC, an independent supplier in Muscat, supplies thermal mass flow meters and mass flow controllers from Sierra Instruments, Brooks Instrument, Alicat, ABB, SICK, Endress+Hauser, CS Instruments, KOBOLD and Tokyo Keiso to customers in Oman and the GCC.

Types of thermal mass flowmeter in this category

Insertion and inline gas meters such as the Sierra QuadraTherm 640i and 780i, SteelMass 640S and FlatTrak 780S, ABB SensyMaster FMT200 and FMT400, Endress+Hauser t-mass 65F and SICK FTMg measure natural gas, biogas, air and process gases. Compressed air meters like the CS Instruments VA 500 and ABB Sensyflow support energy audits. Mass flow controllers including the Brooks SLA5800, SLAMf, GF040, GF80 and GF100, Sierra SmartTrak 100 and Alicat MC and IS-Max series control gas flow in laboratories and processes.

How to select a thermal mass flowmeter

Define the gas or gas mixture, flow range in normal or standard units, pressure, temperature and line size. Choose insertion for large ducts and pipes, inline for smaller lines and best accuracy, and a mass flow controller when flow must be regulated. Check outputs, protocols and hazardous area approvals.
