G1/4'' polycarbonate flow indicator with impeller and filter
Shows at a glance whether water is flowing, also at the lowest flow rates. There is no flow scale and no stated flow range: it only shows flow or no flow. The impeller turns inside a clear polycarbonate body and a built-in 70 to 130 µm filter catches dirt and is cleaned by back-flushing. This low-cost indicator is made for water and water-based liquids up to 1 bar (≈15 psi) and +55 °C (≈131 °F), with flow in one direction. For higher pressure or hot water up to +90 °C (≈194 °F), choose the brass version with a Pyrex glass window.
