Thermatel® Model TA2 Thermal Mass Flow Transmitter provides reliable mass measurement for air and gas flow applications. The powerful, yet easy to use, electronics are contained in a compact explosion proof enclosure. The TA2 offers excellent performance at exceptional value.
Probes can be provided with a variety of process connections, including threads, flanges, or installation through a compression fitting. The sensor will fit pipe sizes of 1 1/2" diameter or larger (2" minimum size with thread connection).
The sensor is protected to prevent damage due to “bottoming-out” if inserted too far into a pipe. When using an insertion probe with compression fitting, the user can adjust the position of the sensor in the pipe to obtain the optimum location. Typically, this will be with the bottom of the probe 1.0 inch (25 mm) lower than the center line of the pipe.

Massflow under control
Massflow gas measurement is independant of temperature and pressure, thus controlling a process gas can be stable and reproduceable. Massflow controllers contain a PID-controller and can be driven through norm signal or field bus. Massflow meters are without actuators and are only for measuring massflow.
