Principle: EMCO flow element type ISB/1EP is used as primary element in flow measurement of liquid, gas and steam according to the differential pressure principle.
The ISB/1EP is especially designed for installations with limited space due to the flow conditioning effect created by the 5 hole design.
ISB/1EP flow element with 5 holes combines a traditional single hole orifice plate with a flow conditioner.
This means that straight pipe run up stream the flow meter can be
reduced from 20 times inner pipe diameter to 5 times inner pipe
diameter
