Q-Flow Variable Area Flowmeters for Gases With Attractive Design

 Our proven Q-Flow is a modern VA flowmeter for gases built on the variable area principle.

Designed in close collaboration with users, it combines our long experience and practical shop-floor requirements.

Measuring Tubes in 2 Sizes

The flowmeters are available with glass tube lengths of 80mm and 140mm. Measuring ranges from 0.06 ln/min up to 50 ln/min for Air @ 1013 bar abs / 20°C
Maximum pressure: 10 bar / Maximum temperature: 100°C

Intelligent Instrument Design

The compact and attractive design enables quick replacement of components

Standard scale for air

The measuring glass is supplied with a standard scale for air (operating conditions 20°C / 1013mbar abs). Conversion factors for other gases and other operating conditions are available.
mm-scale with flow rate table and direct reading scales for other gases and pressures on request.

 

Aluminium body

The bodies are available in aluminium. Sealing material FKM.
