The FLOWSIC200 is used for the contact-free and accurate measurement of flow velocity and flow direction inside tunnels or exhaust ventilation ducts. Ultrasonic technology provides the cross-sectional mean average value of the flow velocity. This device is used for measurement necessary for optimal ventilation control and reducing running costs to a minimum when air flow is dictated by climatic conditions or by traffic.
Measurement in road and railway tunnels
For control of tunnel ventilation
For detection of smoke propagation
Device properties:
Very large measuring distances possible
Non-contact measurement
Extremely rugged components made of titanium, stainless steel, or die cast
Versions for very corrosive tunnel atmospheres
Determination of flow direction
No mechanical moving parts
