AIR FLOWMETER
When a Flow Monitor is not required but simple visual indication will be sufficient; these brilliant Sight Indicators are more than suitable. With their sturdy robust design, resistance to high temperatures and glass dome making visual verification very easy.
A plastic sight air flow indicator or flow meter typically consists of a transparent plastic tube with inlet and outlet ports. Inside the tube, there’s a float or a ball that moves with the flow of air. As air flows through the device, it causes the float or ball to rise, indicating the presence and rate of airflow. The position of the float or ball within the tube corresponds to the flow rate, with higher flow rates causing the float or ball to rise higher. Users can visually inspect the position of the float or ball through the transparent tube to gauge the airflow. This simple design allows for quick and easy monitoring of airflow in various applications, providing a visual indication of airflow status without the need for external power sources or complex instrumentation.
What is an Air Flow Meter?
Flow indicators can be used to confirm visually whether or not there is flow or no flow by observing the movement and rotation of the built in “paddle” which is very useful in situations where it is difficult to ascertain if there is a flow e.g. In a clear liquid. The rising ball type is normally used on gas or air applications where the ball will rise when there is positive flow. )
