Description

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.

Field of application
  • 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
