Azbil to launch high precision mass flow controller with high speed response for rapid understanding of control status


TOKYO – (COMMERCIAL THREAD) – Azbil Corporation (TOKYO: 6845) has announced that it will launch the F4Q digital mass flow controller model on August 18. The new controller offers high speed response and high precision, providing an immediate understanding of the state of the control.

The F4Q’s large LED indicator allows users to immediately know the status of the control while the detailed LCD display allows a quick but comprehensive understanding of the status of the control.

Digital mass flow controllers use an integrated sensor and valve to control gas flow rates. They are used in the production sites of machinery, automobiles, electrical / electronic equipment, semiconductors, etc., in manufacturing equipment requiring high precision gas flow control. In these markets, in order to cope with a decrease in the number of skilled workers and to meet the higher quality requirements due to the miniaturization of electronic components, automatic gas flow control with mass flow controllers is becoming more popular than manual control with needle. valves. However, the widespread use of such regulators is hampered by the fact that general mass flow regulators do not have a display or operation keys, making it necessary to create a system for monitoring the state of the regulation. and setting the target flow, or installing a separate display and control unit.

Azbil, which was quick to introduce controllers equipped with a display and operation keys, now offers the F4Q, with its improved ease of use. Various data can be checked instantly on site thanks to the detailed display which shows a large amount of information, and the control status can be quickly understood by the color and status of the large LED indicator.


  • Instead of the 7-segment, 4-digit digital display of conventional Azbil controllers, the F4Q is equipped with a detailed LCD display. The large LED indicator, which lights up in multiple colors and flashes, allows you to quickly understand the status.

  • High accuracy of 1% of set point over a wide flow range * (with conventional models, accuracy decreases in lower flow ranges).

  • Ultra-fast response in 0.3 seconds.

* Excluding some models

Guided by the azbil Group’s “human-centered automation” philosophy, Azbil aims to make contributions that lead “in series” to the achievement of a sustainable society. It develops and offers products and systems that solve production site problems and meet customer needs.
