HELLO FRIENDS PLZ EXPLAINE ME WHAT IS ORIFICE?AND HOW WE
ARE USING IT IN INSTRUMENTATION
Answer Posted / b.balaji rajgopal
orifice is nothing but a plate having hole at the centre
.when it is placed across a flow line a differential
pressure is created across the orifice due the diff. in the
dia of orifice and pipe line.this diff pressure is directly
proportional to the flow of the liquid.this differential
pressure is given to the differential pressure transmitter.
