Flow measurement in ventilation of fuel cells

Process data

Measuring task: monitoring of the forced ventilation

Measuring point: In the ventilation pipes

Measuring range: 0,5 … 20 m/s

Process pressure: Atmospheric

Process environment: Typically ATEX zone Potential fractions of hydrogen Partially SIL2 required

Application

To ensure hazard free operation of the environmental friendly fuel cell technology, it is necessary to monitor the ventilation of the installation spaces. This control prevents the emergence of potential hazardous atmospheres. The potential loading with hydrogen sets high demands for the sensors and restricts the function of some measuring principles. The Höntzsch vortex sensors are outstanding suitable for monitoring the forced ventilation and available with SIL2 certification.
