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.
