7 Precautions for installation of Purge Device
1.
Please select the appropriate location for installation of the flow Purge Device to ensure easy
adjustment, cleaning, and removal of the Purge Device.
2.
As the float flow rate of the Purge Device is accompanied by a magnetic coupling drive, it is
necessary to ensure that the disturbing magnetic field generated by other working equipment
does not affect the measurement results of the flow meter.
3.
When installing, ensure that the Purge Device is stable and, if necessary, fitted with a mounting
bracket in an appropriate location.
4.
The installation dimensions shall not exceed the given dimensions by too much or too little in
order to avoid tensile or compressive forces acting on the Purge Device.
5.
When the liquid medium contains ferromagnetic particles, a magnetic filter must be installed
before the instrument.
By detecting the static pressure of each
section of the blast furnace body and
calculating the air permeability resistance
index to forecast the furnace condition, so as
to take timely measures to ensure normal
smelting, thus achieving the purpose of
increasing
production
and
energy
conservation.
This is a method of detecting the level of
liquid by measuring the back pressure at the
end of the blowpipe. The Purge Device, which
uses the outlet (secondary pressure) pressure
change control type, continuously and
quantitatively
blows
gas
into
the
measurement object. A differential pressure
transmitter or manometer is usually used to
display the liquid level.
