The Yokogawa RAGK rotameter is designed for measurement of liquids and gases. The conical glass metering tube has a free rotating float. This float is mounted in a vertical pipeline with flow direction upwards. The flow is indicated by the top of the float and can be read from the standard scale on the metering tube or from a connected scale.
The flow metering tube is transparent giving you full insight into the process and position of the float – a scale on the outside of the tube indicates the true flow rate. All the measurement tubes in this series of variable area flowmeters are made of either glass or plastic.
