Field of application

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

Benefits

  • Representative measurement across total tunnel width

  • Very reliable measurement, compared with punctual measurement methods

  • Accurate measurement even of very low flow velocities

  • Long maintenance intervals of up to 5 years

  • Low operating costs due to reliable operation and low maintenance

  • High availability of devices and, therefore, of measurement data also
