	FLOWSIC200
	Flow velocity measurement in road tunnels The FLOWSIC200 is used for the contactless and accurate measurement of flow velocity and flow direction inside tunnels or exhaust ventilation ducts.On base of ultrasonic principle the FLOWSIC200 provides the cross-sectional mean average value of the flow velocity. This measurement device is indispensable when air flow is dictated by climatic conditions - for ensuring optimal ventilation control and reducing running costs to a minimum.


Technical specification

	Interfaces	USB/RS232 (Service), RS485 (option), Ethernet (option)



	Status signals	5 relay outputs for status signals



	System components	2 sender/receiver units, 2 mounting brackets, 1 evaluation unit, 2 connection boxes, 2 connection cables, mounting sets

	Remarks	It is important to measure the air velocity in a very representative way - i.e. cross the whole tunnel. This is the only way to ensure cost optimized ventilation control under normal conditions and safe operation during fires in tunnels.
