Frequently Asked Questions and Answers

What is the role of temperature compensation in a mass flow controller?

Temperature compensation in a mass flow controller adjusts the flow reading to account for variations in ambient temperature. Since the gas properties can change with temperature, MFCs compensate for these variations to maintain accurate flow measurements. This is crucial in environments where temperature fluctuations can impact the accuracy of the flow reading.

What is the difference between a mass flow controller and a volume flow controller?

A mass flow controller measures the mass flow rate of a gas, taking into account its density, whereas a volume flow controller measures the volumetric flow rate at a specific pressure and temperature. Mass flow controllers are more accurate in varying conditions, making them ideal for precision applications where gas properties can change.

How does temperature affect the performance of a mass flow controller?

Temperature changes can affect both the gas density and the sensor’s calibration in a mass flow controller. To compensate for this, most MFCs are equipped with temperature sensors or algorithms that adjust the flow measurement to maintain accuracy. Proper temperature compensation ensures consistent flow control.

What maintenance is required for a traditional mass flow controller?

 Routine maintenance for a mass flow controller includes periodic calibration, cleaning of sensors, and checking the integrity of the control valve. Over time, particulate buildup and contamination can affect the accuracy of the flow measurements. Regular inspections ensure the MFC maintains high performance and reliability, especially in demanding environments such as cleanrooms.

How do mass flow controllers handle different types of gases?

Mass flow controllers can be calibrated to work with specific gases, as each gas has unique properties, such as molecular weight and viscosity. When using an MFC for a different gas, it may require recalibration or gas-specific settings. Pneucleus flow controllers come with a dual-cal feature to have separate calibration for different gases and flow rates e.g 1 L/min O₂ (Cal A) and 5 L/min CO₂ (Cal B).
