General description

Rotameters are suitable for low flow measurement. They can only be used on clean fluids. A typical rotamter has 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.
This rotameter is designed for the accurate regulation of gas flow, providing measurement at the same time. This versatile unit includes four interchangeable floats, each with a different working range. Simply install the float required for the application. Standard flow tables in mL/min at STP are included.

The rotameter is easy to mount. Alternatively, it can be installed on a tripod assembly (order tripod assembly separately). Available with or without needle valve.
