Functional description
The measuring unit is fitted with an effective pressure sensor for measuring the volume flow rate.
The effective pressure is either measured and evaluated manually, or transformed into an electric signal by a pressure transducer.
Nominal sizes | 200 x 100 – 1000 x 1000 |
Volume flow rate range | 45 – 10100 l/s or 162 – 36360 m³/h |
Measurement accuracy | ± 5 % of the measured value |
Effective pressure range | Approx. 5 – 250 Pa |
Measuring unit differential pressure (pressure loss) | 17 – 32 % of the measured effective pressure |
Operating temperature | 10 – 50 °C |
Rectangular volume flow rate measuring unit for the measurement of volume flow rates in air conditioning systems, available in 39 nominal sizes.
For the manual volume flow rate measuring or for the permanent monitoring of the actual value signal.
Ready-to-commission unit which consists of the casing with an averaging differential pressure sensor.
Differential pressure sensor with 3 mm measuring holes (resistant to dust and pollution)
Both ends suitable for the connection of air duct profiles.
Casing air leakage to EN 15727, class B.

Installation and commissioning
Upstream conditions
The volume flow rate accuracy ΔV 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.
