Optional components

• MCUP control unit for use in Ex zone 1+2(ATEXcertification)andClI,Div2/Zone 2

• Spool piece version also complete with p and T transmitters

The FLOWSIC100 Flare standard version contains two FLSE100 sender/receiver units (SR units) and aMCUPcontrolunit(processversion).TheMCUPis used for signal inputs/outputs, determining ref-erence values (standardization) as well as calcu-latingmolecularweight,massfloworstorageofgasvolume.OptionallytheMCUPisapplicableinhazardousareas.TheSOPASsoftwareprovidesaccess to all parameters and contains graphical display of measured values, trend curves and stores all parameter changes and measure-menteventsinanintegratedlogbook.

Installation of the sender/receiver units

• Cross-duct installation: two sender/receiver units are mounted on both sides of a duct – rectangular to the gas flowdirection(typeFLSE100 EX-S).

• One-side installation: Only one single sender/receiver unit (probe version) is mountedataspecificangletothegasflow.Both ultrasonic transducers are installed on theprobewithafixedmeasuringpath.Nospecificalignmentbetweenultrasonictrans-ducersneeded.
