  • Installation: Both lying and standing are possible, and the observation is convenient and clear.
  • (3) Characteristics of flow indicator 1. The surface glass of the window is easy to clean. 2. The glass window can be observed in 180° direction.


The single-tube impeller type observer, also known as the impeller sight glass, is a necessary accessory to observe the flow of the medium in the pipeline. The impeller sight glass is widely used in industrial production equipment such as petroleum, chemical industry, chemical fiber, medicine, food, etc. It can observe the flow reaction of liquid, gas, steam and other media at any time, and is an indispensable accessory to ensure normal production.

I got this to aid with diagnostics of flow issues with vehicle cooling systems. It works great, it doesn't leak, shows you exactly what is going on inside the engine, I am very happy I picked this up.

I got this flow-indicator to help me quickly know what was going on with a hot water recirculating pump system I put in. I wanted to know if the pump was basically continuously running and because the pump had no indicator light and was so quiet while being next to the air system in the house; it was difficult to tell it was actually running. This helped as I could see the impeller spin as water was flowing through it and it made troubleshoot the system a lot easier. This definitely helped me with my specific use case.

Hat im Gegensatz zu anderen Schaugläsern mit Laufrad eine große Durchflussöffnung, wodurch Druck und Durchflussmenge nicht vermindert werden. Ist in meiner Niederdruckumgebung von Vorteil.Allerdings dreht sich das Rad auch erst bei recht hohem Durchfluss (zumindest in der Lage, in der ich das Schauglas eingebaut habe).
