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
The VM400 flow velocity measuring device is a compact and spacesaving device solution for continuous point-to-point measurement of the air velocity in road and railway tunnels or comparable traffic infrastructure constructions.
