TF-2261T PDF

*Specifications are subject to change without prior notice.

The TF-2261T can handle larger flows than flowmeters with medium to large connection sizes among the TF-2000 series mini thermal mass flowmeters. TF-2261T has LCD indication of flow rate and totalization. Also,functions of scaled output pulse and DC4 to 20mA are provided. Furthermore, two-point field adjustable alarm contacts are provided. TF-2261T can be operated by DC24V power supply.


  • · Wide range of process connection for high flow rate

    Connections of 25mm to 80mm are available. They are useful with the extensive use in Air and Nitrogen supply lines etc.

  • · Simultaneous indication of flow rate and totalization

    Large two-line LCD is provided.

  • · Mass flow measurement

    Flow measurement is not influenced by the change in pressure and temperature.

  • · Whole quantity passage detection system

    Pressure loss is very small.

  • · Selection up to six scale ranges can be made.

    Up to 6 scale ranges can be preset using keys.
