Understand the status of control at a glance

The color and state (e.g., flashing) of the LED indicator show the control status.

With the information-rich LCD, you understand the control status in detail.

Accuracy of 1 % S.P. in a wide range of flow rates

High-accuracy control for high and low flow rates.

Great for applications where the flow rate set point changes significantly.

F4Q_2

High-speed response of 0.3 seconds over a wide range of flow rates

Response is fast whether starting control with a fully closed valve or changing the settings.

Even when the flow rates of multiple gases are changed at the same time, their ratio can be retained.

Low-differential pressure structure allows control of low-pressure gas

The pressure loss on a straight flow path is low, so this controller can control low-pressure gas (e.g., fuel gas).

Structure of model F4Q

Usable in a wide temperature range, from -10 to +60°C

The controller can be used in a cold room in winter or near a hot industrial furnace.

Even when the temperature changes greatly, its effect on the measured values is minimal.
