Summary

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.

Features

Gas cutting

Thanks to high-speed response, even when the source pressure changes, there is very little effect on the flow rate. The flame remains stable, which improves the cutting quality.

Baking furnace for MLCCs

The operating temperature range is a wide -10 to 60 °C and the effect of ambient temperature changes on flow rate control is small. A stable atmosphere in the furnace also helps to stabilize the quality of baking.

Gas carburizing furnace

Thanks to low pressure loss, model F4Q can control the flow rate of low-pressure enrichment gas, which is not possible with typical mass flow controllers. Better control of the atmosphere in the furnace can stabilize the quality of carburization.

Culture apparatus

The multiple-point flow rate correction function makes matching to a reference flowmeter possible during onsite calibration. It is not necessary to send the controller to the manufacturer for calibration, so costs can be cut and delivery schedules can be shortened.

Experiments

With an AC adapter, the controller can be powered from a wall socket, eliminating the need for troublesome wiring. Operation, monitoring, and data logging from a PC can be done using the PC loader. An experimental environment can be set up in a short period of time.
