Product Information

Rotameter Model RAMC - Metal Short-Stroke Rotameter

Arrow Rotameter Model RAMC - Metal Short-stroke Rotameter

A float is guided concentrically to a special shaped conicmetal tube. The position of this float is magnetically transmittedto the indicator. The short-tube Rotameter is used formeasurement of flow rates of liquids and gases. Its specialapplication is in troubled, opaque or aggressive mediums.The instrument is mounted in a vertical pipeline with flowdirection upwards.The indicators are exchangeable without influence on theaccuracy.
