Digital mass flow controller model F4Q is a high-performance digital mass flow controller equipped with our original "micro thermal flow sensor".
Equipped with a large LED that shows the control status at a glance and a LCD that shows the status in detail.
Higher accuracy in a wide range of flow rates.
New functions to solve problems with flow rate control.
*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.
*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).
*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.
