Dr. Födisch Umweltmesstechnik 4 Installation Assembly of the weld-in flange The weld-in flange of the FMD 09 is installed according to Fig. 4.2: Weld-in port. installation position of the probe is horizontal or vertical from top. ATTENTION Risk of measuring failures through diagonal installation position! At mounting in diagonal channel the device must be mounted upright so that the connections of the pressure transmitter are aligned vertically.
Page 94: Assembly Of The Probe
Dr. Födisch Umweltmesstechnik 4 Installation Assembly of the probe The probe is assembled into the flange according to Fig. 4.3 and Fig. 4.4 and fixed with the supplied screws and nuts. Thereby the right flow direction of the measuring gas has to be observed: the side marked with has to be flown against by the flue gas! Fig.
Page 95 Dr. Födisch Umweltmesstechnik 4 Installation Fig. 4.4: Installation instruction step 2 – insert probe ATTENTION All holes of the probe need to be inserted into the gas flow. Even if only one hole cannot enter the gas flow (and is stuck in the flange instead), considerable measuring errors will result.
