6 Typical Applications
When using the orifice plate to measure the
flow of corrosive liquids or liquids containing
solid particles, a double-mounted Purge
Device is used to continuously and
quantitatively blow air into the pressure ports
before and after the orifice plate to ensure
that corrosive liquids or liquids containing
solid particles do not flow into the pressure
guide tube of the differential pressure meter
or differential pressure transmitter.
As shown in the diagram above, one
main air supply is divided into multiple
branch air supply sources. If one or more
of the branch sources stops supplying or
adjusts the flow, a change in the main
source pressure will occur. An inlet
(primary pressure) pressure change
control type purge device maintains its
output flow constant.
