The VA 40 variable area flowmeters are suitable for measuring liquids and gases

The standardized device design is available with various connections that conform to standards. The glass measuring cone, protected by a metal sleeve with a viewing glass, makes it easy to read the flow directly and observe the medium.

The suitability for measuring the flow of gases in accordance with the DVGW G260 process sheet has been certified by the DVGW testing station at the Gas-Fired Thermal Institute in Essen.
