Air flow measurement – ventilation

Ventilation is important for maintaining safe operations underground. Correct levels of ventilation must be ensured at all times. Therefore, the supply and exhaust air flows must be measured regularly. Based on the ultrasonic measurement principles, the FLOWSIC200 and the intrinsically safe FLOWSIC60 (Ex ia) can continuously measure air velocity across the entire tunnel cross-section. The FLOWSIC offers maximum reliability in harsh environments and provides real-time measurements at various points, allowing adjustments to be made based on the results taken. The VM400 is a compact air velocity sensor designed to continuously measure the air velocity at single point within a mine tunnel. The VM400 is a cost-effective solution with user-friendly setup for real-time flow measurement.
