Variants, Product details, Additional product information

Volume flow rate measuring unit VME without attachment

Bend, vertical

A bend – with a straight duct section of at least 4H upstream of the measuring unit – has only a negligible effect on the volume flow rate accuracy.

Installation and commissioning

The installation orientation of ELAB must be as shown on the sticker
The installation orientation of XTD/XTS or BTD/BTS is not critical

Upstream conditions

The volume flow rate accuracy Δq_ᵥ applies to a straight upstream section of the duct. Bends, junctions or a narrowing or widening of the duct cause turbulence that may affect measurement. Duct connections, e.g. branches off the main duct, must comply with EN 1505. Some installation situations require straight duct sections upstream.
