Ürün Açıklaması
Flowmeters especially for gases

The VA 45 variable area flowmeters were designed to measure gases. They can be used, for example, in industrial ovens, forges and furnaces, and protective gas and heating systems. 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
