FLOWSIC200
The tunnel flow velocity measuring device for long-term operation
Overview
Product 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.
Key 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
