Yokogawa RAGL Laboratory Rotameter
$24.00
The Yokogawa RAGL Laboratory Rotameter provides accurate visual flow measurement for laboratory and pilot plant applications. Featuring a precision glass tube and a lightweight float, it offers clear indication for both liquid and gas flows. This instrument is essential for research, process development, and calibration tasks where precise, real-time flow monitoring at small scales is required.
The RAGL Laboratory Rotameter is ideal for measuring low flows of liquids and gases, designed with a conical glass metering tube that has a free rotating float, which is mounted in a vertical pipeline with flow direction upwards. In addition, its anti-static metering tubes allow for measurement of small quantities of gas, delivering high accuracy at low flow rates.
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.
