Beschreibung

General description

Durch ihre exzellente Meßgenauigkeit sind diese Rotameter ideal für chromatographische Zwecke. Jedes Rotameter besteht aus einem Flußrohr und vier auswechselbaren Schwimmern. Standard-Fluß-Tabellen (ml/min STP) werden mitgeliefert. Die Rotameter können leicht an jedem Chromatographen befestigt oder mit dem gesondert erhältlichen Tripod-Ständer aufgestellt werden. Mit oder ohne Nadelventil erhältlich.

Rotameters are suitable for low flow measurement. They can only be used on clean fluids. Typically rotameters have a tapered metering tube which is mounted vertically with small end at the bottom and a float which is free to move within the tube. The fluid to be measured enters at the bottom of the tube, passes upwards around the float and out at the top. The increase and decrease of flow causes the float to rise higher or drop to low respectively. The flow rate is hence determined by direct observation of the position of the float in the metering tube.

Application

Calibrated Supelco Rotameter is suitable in mixing medical grade breathable gas with either oxygen or nitrogen.

Disclaimer

The units are not calibrated unless requested. These come with a total of 4 different floats - if they need calibration for each 4 x (calibration charge) plus the price of the meter.
