Thermal mass flow controller F4Q

Does your gas cutting machine automatically provide reliable ignition and stable flame power? Even with sudden pressure fluctuations? Our digital mass flow controller, the Model F4Q, is designed specifically for gas cutting machines. Two important features: 1. SP ramp function: This feature allows a controlled and gradual increase in flow rate, preventing the sudden supply of O2 from extinguishing the ignition. 2. MEMS technology: Experience fast response times that keep your gas flow constant regardless of fluctuations in the pressure source. It features a large LED display for at-a-glance control status and an LCD display for detailed status information. It offers greater accuracy across a wide range of flow rates. Its new functions solve problems with flow rate control. • Understand the control status at a glance. The colour and state (e.g. flashing) of the LED indicator show the control status. The information-rich LCD provides a detailed overview of the control status. • It has an accuracy of 1% S.P. across a wide range of flow rates. High-accuracy control is possible for both high and low flow rates. This is 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. The response is fast when starting control with a fully closed valve or changing the settings. Even when the flow rates of multiple gases change simultaneously, their ratio can be retained. • The low-differential-pressure structure enables control of low-pressure gas. Pressure loss on a straight flow path is minimal, enabling control of low-pressure gases (e.g. fuel gas). • It can be used within a wide temperature range of -10 to +60°C. The controller can be used in cold rooms in winter or near hot industrial furnaces. Even when the temperature changes greatly, its effect on the measured values is minimal.
