high pressure mass flow controller

Kelly Pneumatics, Inc. offers a reduced cost, single or dual-valve design, Mass Flow Controller for high volume flow applications. The unit is calibrated for up to +-1% accuracy (full scale) for flow rates of 0-300 lpm. For greater accuracy, the unit can be customized to +-2% of reading, for flow rates above 2.5 lpm. Gas/Back Pressure: 0 to

March 12, 2018. Measurement, Instrumentation, Control & Automation. Vary-P control valves were already introduced by Bronkhorst in 1985 for controlling high-pressure gas flow with high pressure differences of up to 400 bar (later on extended to 700 bar!). The control valves - usually integrated in a mass flow controller (F-230 series) - are

Leading edge flow control featuring extremely fast response times, very high accuracy, pressure insensitivity are available in the SAM and Aera digital MFC product offerings. Highly stable and very accurate vapor delivery is provided with the Aera AS and GS family of vapor delivery products.

High accuracy and resolution are achieved with the differential pressure sensor measuring pressure drop across a laminar flow channel, which is linearly 

Most mass flow controllers have internal control valves that only operate with a limited differential pressure. This can be problematic for metering gases into high pressure applications, such as research reactors. The solenoid actuated control valves in the MFCs have orifices that are carefully selected for the intended differential pressure.

For high pressure applications, Alicat's MCQ series controllers handle ranges between 30 PSIA and 320 PSIA (1.03 to 22 bar). These controllers offer the great

High-pressure mass flow controllers are often used to control gas flow in chemical processes, both in research and in production 

An MFC for gas automatically controls the flow rate at a given set point. A thermal mass flow controller is designed to deliver smooth, stable, accurate, and repeatable gas mass flow control

dramatically from conventional mass flow controllers (MFC) in its very theory of operation. By developing the FCS ® around non-conventional methods, highly accurate flow control is achieved – accuracy that is impossible to achieve with traditional pressure-based

Mass flow controllers are instruments that measure and control the flow of gas in reference to a specified flow rate. When adjustments in gas flow are required to maintain that rate, the feedback from the sensor is used to create an electronic signal to send to a control valve.
