Guided Wave Radar Level Sensor
Now Offers ATEX and CSA Approvals for Hazardous Locations
Elburn,
IL –Monitor Technologies LLC announces
the availability of ATEX and CSA certifications
for it's Flexar(TM) guided wave radar continuous
level measurement product line. The ATEX certification
is Ex II 1/2 GD T75 ... 150C. CSA certification
includes Class I, Division 1 & 2, Group B,
C and D as well as Class II, Division 1 & 2,
Groups E, F and G. CSA certifications apply to
both Canada and the USA. These approvals allow
the benefits of guided wave radar technology to
be extended to areas where hazardous and explosive
vapors and dust exist worldwide.
Flexar(TM) guided wave radar product is a continuous level measurement device
using TDR (time domain reflectometry) principles where radar pulses area focused
to the material surface by the unit's wave guide (typically a heavy duty cable
or rod) and the time-of-flight of the pulse reflection back to the instrument
electronics is directly related to the empty distance in the vessel and the material
level.
Guided wave radar technology has proven successful and the best choice for virtually
all powder and bulk solids application as well as a multitude of liquids applications.
Monitor Technologies uniquely combines this proven level measurement technology
with five decades of expertise in powder and bulk solids level measurement along
with the industry leading PC-based inventory management software package.
Monitor Technologies LLC is a leading supplier of level, flow, particle emission
and aeration instrumentation for the worldwide powder and bulk solids market.
The experience and market knowledge gained over five decades has earned Monitor
a reputation for providing high quality and reliable product solutions. Monitor
is located in Elburn Illinois, give us a call today and let us put our creative
solutions to work for you!
SiloPatrol® SE Measuring coal powder levels when nothing else will work ….
Coal-fired power plants are commonplace around the
world. In order for these power generating stations to create
huge amounts of electricity the turbines need to be feed with steam
and the steam created by boilers that are fired by … yep,
coal. But coal as it comes from the mining operations is not
what is fed to the burners. First it is ground or pulverized
into powder. It is not unusual for the coal powder to be stored
in silos awaiting the demand for it to be fed to the burners. The
inventory of coal powder in these silos needs to be monitored to
allow for efficient operation of the power plant.
So, how do we monitor the inventory of coal powder in a silo? Not
easily. In one typical application the power plant personnel
found that the only technology that would work reliably is the modern
smart weight & cable system from Monitor Technologies LLC, the
SiloPatrol® SE.
Anhui Tongling power plant in Anhui province in China had tried
almost ever technology possible to get a reliable level measurement
in their 5 coal powder silos. Radar, ultrasonic and others
were tried, but none worked reliably. It wasn’t until
Beijing Conasen walked in and proposed that the Tongling plant use
the SiloPatrol SE smart cable-based inventory monitoring system that
the power plant personnel found a reliable solution.
Mr. William Yuan, sales manager for Beijing Conasen indicates that
the power plant tried many major brands of ultrasonic, radar, and
other technologies but that due to good relations with the Tongling
plant personnel he was able to sell three SiloPatrol SE model SMU
sensors and an HMI operator interface to them. The units were
installed by plant personnel. Because of the heavy amount of
coal dust in the silos an air purge using dry compressed air was
used. The SiloPatrol sensor incorporates the patent-pending
use of Hall-effect sensor technology, a split-compartment enclosure,
microcontroller, redundant optics and many other valuable features
and technology to ensure reliable measurement even in challenging
dust applications like coal powder.
The SiloPatrol SE system has been working reliably and the plant
has since purchased two additional sensors and connected them into
the same HMI operator interface. This same sensor technology
is working reliably at other coal-fired power stations in China as
well.
