RAQN Rotameter Flow Meter
Brand: Yokogawa Electric CorporationThis type of 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 on the standard scale of the metering tube or on a pin-on scale.
