Yokogawa RAGL 41 Laboratory Rotameter

The Yokogawa RAGL 41 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.

Measurable flow rates:

• Water 68°F (20°C); 0.002 l/h bis 110 l/h
• Air 68°F (20°C; 1 bar abs.): 0.1 l/h bis 3 500 l/h

Measuring range:

• K metering tube; 10:1
• M metering tube; 20:1 (10:1)
• L metering tube; 20:1

Max. Temperature:

• Fitting material SS; 212°F (100°C)
• With option /MV; 266°F (130°C) (not for PP-Rotameter)
• Fitting material PP; 176°F (80°C)
