Digital Mass Flow ControllerModel F4Q
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).
Structure of a typical mass flow controller
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.
Application
Brazing and burner work
Thanks to high-speed response, when the flame intensity is changed, the flame instantaneously stabilizes,
contributing to stable product quality and reduced takt time.
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.
