Monitor and control the flow rate in your pneumatic system with this flow controller from Festo. You can use it to detect leaks and test tightness in the end device, helping you manage your energy costs and maximise the efficiency of your setup. It's ATEX-certified, so is suitable for use in potentially explosive atmospheres. An illuminated blue LCD display can rotate through 270˚ to allow easy monitoring from any position. To allow you to adjust your system easily, there's an integrated flow control valve.

• IP65 rating means it's dust-tight and stands up to low-pressure water jets
• Operating temperature of 0°C to +50 °C makes it suitable for use in hot industrial environments

• Chemical processing plants
• Paint spraying facilities
• Flour mills

When choosing a flow sensor, you need to consider the viscosity of the fluid being measured, the likely minimum and maximum flow rates and the system pressure. You should also think about process temperature (whether you want time measurement or totalising flow measurement), and output as a display or a signal.
