1: Effective pressure sensor
2: Measuring transducer
3: Casing


The volume flow rate measuring unit is fitted with an effective pressure sensor for measuring the volume flow rate. The effective pressure recorded with this sensor is either measured and evaluated manually, or transformed into an electrical signal by a measuring transducer (effective pressure transducer).

  • VME/400 × 200
  • Δpw = 100 Pa (manometer reading of effective pressure)
  • Volume flow rate qv in m³/h

Unit data

  • K value from table: K =218 m3/h (60.5 l/s)


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 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.

Space required for commissioning and maintenance

Sufficient space must be kept clear near any attachments to allow for commissioning and maintenance. It may be necessary to provide sufficiently sized inspection access openings.

Product illustrations do not show any installation situation details. If an attachment requires a certain installation orientation, this is specified on a sticker on the product.
