In the Pharmaceutical
industry, most problems that were encountered in tubular glass gauges for level
measurements are now resolved by magnetic level gauges. Tubular glass gauges
are placed parallel to the vessel at a suitable height and are mounted with fittings,
which enables to maintain the pressure and seal at both ends of the tube. But,
it has been noticed that this type of installation is unsuitable for certain
liquids. There is a possibility that the glass tube would be fractured or one
or both seals would suffer from leaks. Consequently, the liquid could escape
outside the gauge. For this reason, in case of critical liquids in the
Pharmaceutical industry, the design of tubular level gauges is found
unsatisfactory.
In course of time, magnetic
level gauges have replaced tubular level gauges as in case of magnetic level
gauges, there are practically no probable leak points. The main advantage of
Pune Techtrol’s magnetic level gauge is its “all metallic” construction. Level
indicating part of the gauge does not come in contact with the liquid. There is
no presence of fragile glass tubes, which can break and cause safety hazard.
The visibility of the level readings is vastly improved. The instances of
maintenance are very less. The initial installation is simpler as compared with
other gauges. Without interruption in the level measurement process, addition
of switches and transmitters can be performed. Because the addition of switches
and transmitters is possible, technique of dual redundancy has led to improved
security. The Return on Investment (RoI) benefits are more.
Additionally, Techtrol’s magnetic liquid gauges
are superior to the tubular glass gauges due to the various factors mentioned
below.
Long-distance visibility
Tubular glass level gauge
indicators enable the personnel to take readings of level from a maximum
distance of three metres. In case of Techtrol’s magnetic type level gauge, it
is possible to note the level reading from a distance of 10 metres or even somewhat
more. This is possible due to a fluorescent and bright contrasting colours of
the flag. More sophisticated visual indicators also allow viewability up to 30
metres.
Lesser maintenance costs
In case of sight gauge level
indicators, it is mandatory to clean them on a periodic basis and check for
leaks. The process liquids can cause build-up, etching and scaling on the glass
due to which the sight glass can become unreadable. The advantage of magnetic
level gauges of Pune Techtrol is that they are almost free of maintenance
because there is no contact between the process liquid and the indicator.
Lesser risks
The chemical compatibility
of a liquid needs to be ensured only in case of the float, gaskets and the
metallic chamber. On the other hand, in tubular glass level gauge the liquid
must be chemically be compatible with all the materials that get wet, such as
the gaskets, sealants, metal and glass.
The possibility of rupture
of a magnetic level gauge is not there at all due its “all metallic”
construction. The float chamber of the magnetic level gauge is made up of the
same metal as that of the main vessel. In the tubular glass level gauges,
extreme temperature or pressure can lead to a fracture. So, the magnetic level
gauge and the surrounding piping are equally secure. The mounting of the
switches, transmitters and indicators is external. So, they are not affected by
corrosiveness, toxicity or other harmful effects of the liquid.
Other salient features
Pune Techtrol manufactures
magnetic liquid level gauges that can accommodate in parallel, micro-switches
and adjustable bistable alarm contacts with reed switches. The design of the
magnetic float system allows for 360 degrees magnetic coupling. These gauges
can be fitted with radar transmitters. Indication of a float failure is also
possible. The indicator housing is typically made of Aluminium. These gauges
are hermetically sealed and filled with inert gases. When installation is
required within a limited space, magnetic level gauges are optimally suited. For
the float and the guided wave radar to work independently, the chamber can be
fitted with special baffle plate. A different range of materials is used for
the construction. Easy mounting is possible with a flanged connection. No power
supply is essential for level indication. Overall, this is an economical
measurement solution.
Tests recommended for magnetic level gauges
Techtrol’s gauges are
subjected to a large number of tests to ensure reliable and precise level
measurement. They are verified for the Seismic test, Radiography on butt weld
joints, Ultrasonic test on butt weld joints, Vacuum test, PMI test, Dye
penetrant test, Helium leak test, Pneumatic test and Hydrostatic test.
It can now be easily
understood that a magnetic level gauge is a very suitable choice when there
is need of visibility from a long
distance, minimization of maintenance, lessening of fugitive emissions or media
leakage or personnel safety.
