Accurate Flow Measurement for Optimal Performance
Precise volumetric flow measurement plays a key role in ensuring efficiency and quality across industrial processes. Monitoring volume flow with high accuracy supports system reliability, optimizes energy consumption and helps maintain compliance. Innovative solutions provide consistent results – even under demanding conditions.
High-end transmitter
Volumetric flow measurement determines how much air or gas passes through a duct or pipe within a given time. One common method uses differential pressure transmitters, which calculate flow based on the pressure difference across a defined restriction (such as an orifice or Venturi nozzle). This approach is highly reliable and widely used in ventilation and process control systems.
Once the transmitter provides real-time flow data, the extraction system (exhaust) can automatically adjust its throughput. For example, if the measured flow is too low, the control system increases fan speed or opens dampers to ensure sufficient extraction. Conversely, if the flow exceeds the setpoint, the system reduces the airflow to maintain efficiency and prevent energy waste.
By integrating differential pressure transmitter like the P 26.2 with intelligent control, facilities achieve precise airflow regulation, improved energy efficiency, and stable process conditions.
Volume flow applications
Accurate flow data with volume flow measurement enables better resource allocation, compliance with energy management standards, and data-driven decisions for efficiency and sustainability.
Key Applications:
- Energy Management in Ventilation Systems: Measuring air volume flow allows companies to monitor and allocate energy costs fairly across production areas. It supports optimization of heating, cooling, and air distribution, reducing operating expenses and improving sustainability.
- Process Control in Industrial Drying and Coating: In sectors such as automotive manufacturing, load-dependent volume flow control in curing ovens significantly reduces energy consumption without compromising product quality. Dynamic adjustment of airflow based on demand minimizes gas and electricity usage.
- Cleanroom and Climate Control: Maintaining precise airflow is critical for controlled environments in pharmaceutical, electronics, and food industries, ensuring compliance with stringent standards.
- Filter and Fan Monitoring: Continuous measurement helps detect pressure drops and maintain system efficiency, preventing downtime and reducing maintenance costs.

High-end transmitter
for demanding applications
The precise differential pressure transmitter in the P 26.2 series meet the highest demands for measuring accuracy and stability, even in small pressure ranges. This means that pressure cascades in clean rooms or clean production zones, for example, can be continuously monitored - for consistently high production quality and reliable personal protection. Thanks to the inductive measuring principle, excellent long-term stability and optimum temperature behavior are guaranteed. The slightest pressure deviations are detected immediately. The P 26.2 differential pressure transmitter is also equipped as standard for volume flow measurement.
