The sprinkler measuring orifice SMB is used for flow measurement in stationary sprinkler systems. The device works according to the principle of differential pressure.The SMB is integrated into the pipeline as an intermediate flange assembly. A differential pressure occurs at the orifice, which is proportional to square of the volume flow through the pipeline. The differential pressure is indicated by a differential-pressure gauge. Scaling of the pressure gauge is in flow units. The pointer position immediately indicates the current volume flow rate through the pipeline. The measuring orifice SMB-OE displays the differential pressure as a percentage value on a pressure gauge. The operator can read the equivalent volume from a label fixed to the pressure gauge. Thanks to its particular articulate design, integration of the SMB is possible in any flow direction. The display pivots by 180 degrees in both directions. In case of vibrations in the pipeline orifice and pressure gauge can be decoupled by the Minimess hose connection (pressure gauge for wall mounting)

Operating Principle
A differential pressure arises at a pipe constriction, which is proportional to the square of the flow rate through the pipe.
The resulting differential pressure can be recorded with a meter and can be directly indicated as flow rate on a scale.
