In manufacture of drugs, precision in level measurement is a huge
challenge. Ensuring that the final product adheres to the stated tolerances has
traditionally not been simple. Level measurement in the Pharmaceutical industry
is associated with disparate challenges such as the need of repetitive level
measurements to avoid catastrophes, harmony with bioprocess standards,
verification of calibration as per ISO/FDA standards, and system reliability in
the face of altering process conditions. This industry involves the use of
mixers, bioreactors, fermenters, and prep tanks. These containers undergo
alterations in density, temperature, and pressure. Hence, accuracy in level
measurement is a tough task. Some containers have inbuilt nozzles and agitators
due to which application of certain types of mechanical level measurement
devices becomes problematic. Another issue is that validation of calibration of
level measurement transmitters is mandatory. For this, it becomes essential to
remove the container from the process line for the ‘wet calibration procedure.’
Future of level measurement in the Pharmaceutical industry
A new generation of sensors has been developed that can provide reliable
level measurement of media with a dielectric constant > 2. Some examples of such
media are a skin lotion and a sun screen. Another innovation avoids the
development of condensation in the housing of the sensor. Efforts are in
progress to have a very short response time. FDA-compliant materials are used
to develop the sensor parts that can come in contact with the media. Media that
could not be measured till date can now be accurately measured by the extended
level of measurement of the new sensors. Another trend is to use American
Sanitary standard 3A materials for sensors because they have the ability to
resist sterilization or cyclic cleaning. The Guided Wave Radar (GWR) method is
fast gaining ground as a reliable method of level measurement. GWR has been
overtaking all areas of measurement previously held by ultrasonic and capacitance
systems. The use of capacitive sensors is on the rise. After approaching the
active surface, they react if the material exceeds a specific capacitance. They
do not have moving parts and do not undergo wear and tear.
Latest solutions of level measurement in the Pharmaceutical industry
In production of drugs, more focus is being made on high-value individual
machines. Production plants now opt for smaller batches. This has resulted in
flexible manufacturing lines. The tighter process control in these prevents
losses of expensive materials and products. In this scenario, small volumes of
materials are moved frequently. To avoid emptying and overfilling of production
and transport vessels, a very high degree of level measurement technology is
becoming increasingly mandatory. This has become possible due to optoelectronic
sensors. These have a very high accuracy of up to 0.5 mm. They ensure optimal
volume utilization, even if the vessel diameter reduces. They are not adversely
affected by magnetic fields and vibrations. Their operation is independent of
the liquid’s dielectric constant, conductivity, temperature, pressure,
viscosity, and density.
Use of magnetic level gauges over traditional tubular glass gauges
In the Pharmaceutical industry, most problems that were encountered in
tubular glass gauges are now resolved by magnetic level gauges. Tubular glass
gauges were used in the past for level measurement and had the following
problems. Such gauges were placed parallel to the vessel at a suitable height and
were mounted with fittings, which enabled to maintain the pressure and seal
both ends of the tube. But, it was detected that this pattern was unsuitable
for certain liquids. There was 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 was
found unsatisfactory.
In course of time, magnetic level gauges replaced tubular level gauges as
the probable leak points are considerably reduced. Because there is no presence
of fragile glass, safety is better. The visibility of the 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 was possible, dual technology
redundancy led to improved security. The long-term cost of ownership was
lesser. The Return on Investment (RoI) benefits were more. Pune Techtrol’s
magnetic level gauges provide all the above features.
