Low-flow gas applications benefit most from thermal mass flow meters. Directly measuring gas mass flow, the meters find widespread use in building management systems, environmental applications, control systems for industrial processes, and management systems for energy management.
These meters have come a long way since they were first introduced in the 1970s. They have gone from being analog into digital, from measuring low to high flows, and from being used mostly in laboratories to being used in industrial settings and potentially dangerous locations. In fact, in certain potentially dangerous locations, such as in the process of well plugging, the precise measurements provided by these meters can be crucial.
