Air flow meter is know as air consumption meter. It is a device that measures how much air is flowing through a tube. They does not measure the volume of the air passing through the tube, it measures the amount of mass flowing through the device in a defined time segment. This is just an application of mass flow meters for a special medium.
Air Flow Switch is designed to prove airflow control in wide variety industrial applications. An air flow switch is used as a volume booster, using a low flow pneumatic signal to produce an output pressure with a higher flow capacity. The air flow switch is available for either positive or negative air pressure. Air flow switch is also used to signal the air flow from ventilation units.
Air Fuse Valve is designed for pneumatics. This is designed for non-lubricated systems. This valve is tamper resistant. Airflow is stopped 100% to allow for repair. It activates when air pressure drops to 20 psi. This is made of high strength, lightweight, anodized aluminum alloy. The flow capacity of this valve is 1.0 Cv. The valve stops all airflow, preventing whipping hoses.
