The sprinkler measuring orifice SMB is used for monitoring efficiency of pump in test piping of stationary sprinkler systems. It works according to the principle of differential pressure created with an orifice plate.

The SMB is integrated into the pipeline between flanges as a wafer flow-meter. 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. We calibrate on bench the gauge according the flow rates. The instant value of flow rate is directly read on the dial.

The version SMB-OEdisplays the differential pressure as a percentage value. The operator can read the equivalent flow in m³/min on a label fixed to the casing.

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 Sprinkler system, the SMB may be fitted with flexible capillaries, to remote the gauge.
