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.
