Flow Indicator Sight Glass

Flow sight glass indicator, also known as flow indicator or sight glass, is an industrial pipeline element, used to observe the flow and reaction of liquid, gas, steam and other media in the pipeline. It does not directly measure the flow of the fluid, but through visual observation to confirm whether the fluid is flowing in the pipe and the state of the flow. Flow sight glass indicator senses the flow state of the medium in the pipeline through the internal flow indicator mechanism, and displays this information in an intuitive way. When the medium flows in the pipeline, the flow indicator mechanism is affected by the force or pressure generated by the medium flow, so that the corresponding action or position change occurs. And this change is perceived by the external observer through a specific way (such as the blade or float in the observation window), so as to achieve the monitoring of the medium flow.
