VARIABLE AREA FLOWMETERS - ROTAMETER

The Variable Area Flowmeter is one of the oldest and most mature principles in flow measurement. Right from the outset, the Rotameter convinced with its simple design: a float rises inside a conically shaped glass tube as the flow increases and its position on a scale can be read off as the flow rate. Felix Meyer, the founder of "Deutsche Rotawerke“, was quick to recognise the importance of the variable area flowmeter developed by Karl Küppers who found the perfect shape of a float that causes it to rotate and therefore provides self-stabilization.

Metal Short-Stroke Rotameter Model RAMC

Metal Short-Stroke Rotameter Model RAMC

The short-stroke Rotameter RAMC allows the measurement of high flow rates using a relative short metering tube. With its all stainless steel design it is meant for the safe measurement of a variety of liquids, gases and steam.

Small Metal Rotameter Model RAKD

Small Metal Rotameter Model RAKD

The RAKD Rotameter is used for measurement of liquids and gases and is highly accurate, particularly for low flows and high pressure applications.

Rotameter Model RAGN

Rotameter Model RAGN

The Rotameter RAGN is the world´s first Glass Rotameter suitable for SIL applications and is designed for continuous flow measurement of liquids and gases.
