Maintenance
1: Effective pressure sensor
2: Transmitter (optional add-on part)
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).

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
Upstream conditions
The volume flow rate accuracy Δqᵥ 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.
