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.
