A typical rotameter 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)
