FAQs
What is the difference between a flow regulator and a pressure regulator?
A flow regulator maintains a constant gas flow rate regardless of pressure changes, while a pressure regulator controls the output pressure of a system. Flow regulators are ideal for applications where volume consistency is critical.
Can flow regulators be used with liquids?
Flow regulators are typically designed specifically for calibration gas applications.
How do I choose the right flow rate for my application?
The correct flow rate depends on your system’s requirements, gas type and operating conditions. Boiswood’s technical team can help you specify the right regulator based on your application.
Are flow regulators adjustable?
Most flow regulators are fixed-flow devices, meaning they are calibrated to deliver a specific flow rate. Adjustable models do exist but are less common and typically used in specialised setups.
Can flow regulators be supplied pre-fitted to cylinder connectors?
Yes, Boiswood offers flow regulators pre-fitted to our cylinder connector range for plug-and-play installation. This reduces setup time and ensures leak-free performance.
Do flow regulators require maintenance?
Flow regulators are generally low-maintenance, but periodic inspection is recommended to ensure performance, especially in systems handling aggressive gases or operating continuously.
