Inventory Monitors Saves Time and Increases Concrete Plant Safety
Effective concrete plant operation requires good management of your raw material inventories. Materials like cement, flyash and aggregates are often stored in silos or bins. In such cases it is necessary to check periodically to see how much cement or flyash you have on-hand in order to run continuous and consistent concrete mix. In the past, plant personnel have had to climb to the top of the silos in order to “tape” the empty space distance to determine how much material you have remaining. Not any more….
The SiloPatrol(r) SE smart cable-based sensors are available to perform the task of measuring the inventory level of cement, flyash and aggregate automatically, on-demand and without the need for your operator or plant personnel to climb silos or do much of anything. The smart cabled-base sensors automatically lower a weight & cable sensing mechanism into the silo until it contacts the material surface. Upon contact the weight & cable system is immediately retracted and the measurement is relayed to the plant control system or operator. Electronic sensing mechanisms and sensor software control all functions of the sensor to ensure the proper travel of the weight & cable assembly to ensure accuracy and reliability. These sensors are easy to install and also virtually maintenance free, requiring only a periodic inspection usually once or twice per year. Once the material level measurement is obtained, a variety of operator interface devices is available to calculate and display material volume, weight and %-full information. A PC-base software package is also available that can automate report generation, send emails to suppliers or corporate locations and allow remote viewing of the graphical interface.
The SiloPatrol SE uses the time-proven weight and cable techniques and combines patent-pending technology, a new split-compartment enclosure design, state-of-the-art optics, SMT (surface mount electronic technology) and other valuable features to produce a rugged, reliable and accurate measuring system designed for the harshest and most dynamic conditions. The SiloPatrol SE can help keep your plant running smoothly and increase personnel safety.

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.
