Intended use 1 . 5 Purpose of the device The FLOWSIC200 measuring system is used for non-contact measurement of flow velocity and air temperature in traffic tunnels (road, railroad tunnels) or can be used in other tunnel facilities. Correct use ...
Improper use or handling can cause health or material damage. Read this Section carefully and ensure you observe the safety precautions during all work on the FLOWSIC200, as well as the warning and caution information in the individual Sections of these Operating Instructions.
Instructions. The manufacturer bears no responsibility for any other use. Do not carry out any work or repairs on the FLOWSIC200 not described in this Manual. Do not remove, add or modify any components to or on the FLOWSIC200 unless described and specified in the official manufacturer information.
To ensure the power supply for all connected measuring points, follow the instructions on p. 45, §3.3.2.2. The S/R units of the FLOWSIC200 must be set to address 1 ... 7 on the hardware side ( p. 36, §3.2.2.2).
Product description Functional principle 2.1.3 The FLOWSIC200 works according to the principle of ultrasonic transit time difference measurement. Sender/receiver units are mounted on both sides of a tunnel at a certain angle of inclination to the gas flow ( Fig. 4).

FLOWSIC200 during parameterization ( p. 92, §4.3.3). The device then calculates the calibrated flow velocity v from measured value x of the FLOWSIC200 according to the following formula: v = Cv2 ·...
Check cycle 2. 4 A check cycle can be triggered on the FLOWSIC200 to test whether the device components are functioning correctly. The check cycle can also be triggered automatically (the interval can be set using SOPAS ET) and/or via a digital input ( p. 20, §2.2.3). Any deviations from normal behavior are output as a warning or error.
To set/change the parameters, carry out the following procedure: Connect the measuring system to the SOPAS ET program, scan the network and add the required device file ( MCU, FLOWSIC200 M/FLOWSIC200 H/FLOWSIC200 H-M ) to the current project ( p. 64, §4.1.4).
“Maintenance” ( p. 67, §4.2) and enter the Level 1 password ( p. 64, §4.1.4). Open device file “FLOWSIC200 M” or “FLOWSIC200 H” or “FLOWSIC200 H-M” for the sender/receiver unit, select directory “Configuration / Application Parameters”, set the sender/receiver unit to “Maintenance”...
Select directory “Configuration / Application Parameters“ ( p. 70, Fig. 57). In field “Installation Parameters“ ( p. 70, Fig. 57), enter the path length and installation angle ( p. 71, Fig. 58). The settings are uploaded to the FLOWSIC200 after switching from “Maintenance” to “Measurement”.
Checking the signal waveform allows an assessment on the quality of the received ultrasonic signals. For display on the screen, open the device file “FLOWSIC200 M” or “FLOWSIC200 H” or “FLOWSIC200 H-M” and select the directory “Diagnosis/Sensor values” (operating mode “Measurement”).
Default values from the factory are Cv2 = 0, Cv1 = 1, Cv0 = 0. Calibrate temperature measurement The accuracy of the acoustic temperature measurement with the FLOWSIC200 is a square function of the measuring path and sound velocity of the real gas under standard conditions (...
SOPAS ET ( p. 93, Fig. 83). To do this, connect the measuring system to SOPAS ET, select device file “FLOWSIC200 M“, “FLOWSIC200 H” or “FLOWSIC200 H-M“ and set the measuring system to “Maintenance” ( p. 67, §4.2).
Regular maintenance activities can be carried out by the plant operator. Only qualified personnel according to Section 1 should be allowed to do the work. If desired, SICK Service or authorized Service support centers can carry out all maintenance work. SICK offers a range of economical maintenance and repair agreements.
Malfunctions Implausible measured values 6.1.1 In some cases, the FLOWSIC200 delivers measured values that do not seem plausible or have too large short-term fluctuations. Symptom Possible cause Action Measured values are Incorrect parameter setting of measuring path and Check parameter settings...
