History Around Coal Mining

We love a little bit of history, and coal mining has an interesting tale to be told.

One of the largest mining industries, mining for coal started out in the 18th century and boomed all the way to the 1950’s.  Although maybe not as huge as some other mined commodities, coal is still a valuable form of energy for open-pit extraction.

Interestingly, tunnelling into the earth to pull the coal was the initial method, but had to be stopped due to the perilous vapours that were emitted (carbon monoxide, carbon dioxide, and hydrogen sulphite) deadly to say the least.

The sensors now used in the coal mining process have helped with detecting these harmful vapours and have progressed from the mining’s canary method.

What is the Miners Canary?

If you know mining, you would have heard of this amazing story.  Very simply, miners would take a canary in a cage down with them as they descended. Canaries were known to be very sensitive to odourless vapours, such as carbon monoxide, and they would show effects of distress, rocking from side to side, before falling off their perches.

While not a very animal safe procedure, it was known to have saved many human lives.  After a time, the canary method of detection was stopped as it proved not to be as effective as they assumed it was.

In steps the Pellistor

The Pellistor was introduced as a catalytic sensor and was able to detect a very wide range of toxic vapours and flammable gases.

Due to limitations, such as malfunction when exposed to chemicals with chlorine, sulphur, halogen, and any metals containing silicon or lead; as well as high costs to maintain the pellistor, this method was withdrawn.

Infrared LED-based Gas Sensor

The more modern and more effective method is the infrared LED – based Gas Sensor.

The advantages of this method are:

  • A wider measurement range
  • A rapid response rate
  • Background gases do not affect the gas sensor, as it did with the Pellistor
  • Each gas can be detected and measured separately

UWT Level Control’s Measuring principles for level detection / level measurement

The measurement methods that UWT distinguish between are, Level Detection and Continuous Level Measurement.

Level detection is used to measure a predefined fill level, and continuous level measurement is the continuous checking of the level of the medium in a silo or a hopper.

The different measuring principles which are used in the field of level measurement technology are explained here in detail.

UWT’s Level Detection Measurement Method

Level detection is used to avoid overfilling or downtime in silos and containers.  Level limit switches are also used as spillage detectors in pipes or for the measurement of levels in interface applications.  The switching point depends on the installation position of the sensor and its configuration.  The information is analysed and transmitted via a digital signal to the control unit directly or via a fieldbus.  Other operations and alarms such as a filling stop and start, or demand signal can thus be triggered.  Level switches are used in solids, liquids or sticky media.


UWT’s Measurement method – continuous level measurement

Continuous level measurement,  the constant determining of the fill level, is already built into many silos, containers or process vessels, in order to implement optimum material logistics. For these measuring applications various factors such as silo and vessel geometry, sensor mounting position, the properties of the medium such as flowability, bulk density, conductivity, moisture, dust and adhesion all play a role and must be considered when selecting the right measuring principle.

The HM-E AND HMP-E FLOW METER VERY VERSATILE – brought to us by Anderson-Negele


Anderson-Negele’s HM-E and HMP-E Flow Meters can be used successfully in applications without conductivity, such as:

  • oil measurement (careful: particles / viscosity)
  • water: reverse osmosis water i.e. in soft drink production, condensate, pharma WFI (water for injection) and others
  • where ever it can replace mass flow


  • For water batching
  • For water control (hose applications)
  • Hot water dispensing (the wash down of cream transport)


  • Filling machine, as it is fast acting
  • Drum rinsing, as it is compact


  • WFI batch stations
  • Filtration monitoring

A look at HM-E and HMP-E – turbine flow



The Principle of Operation

As shown by the first Anderson-Negele image, we have A and C, upstream and downstream flow straighteners, respectively.  They stabilize the incoming liquid, so that the flow will move through the rotor B linearly.  On contact with B, the liquid then causes the rotor to rotate a shaft which is part of the downstream flow straightener.  As a result, the velocity of the liquid moves through the meter.

We move to the second image, where we see the signal probe (1) which contains components which generate an electromagnetic field (3) made possible by the internal oscillating circuit named 2.  An induction current or eddy current is produced in the turning rotor vanes.  The electromagnetic field, which is generated, counteracts the magnetic field from the oscillating circuit, which causes a change in the oscillating circuit voltage.  Number 4, the integrated amplifier changes into a pulse signal.  Because the frequency created by the vanes corresponds with the rotation of the rotor, the pulses put out equal to the volume of the liquid moving through the meter.



With proper location, you will get the following from Anderson-Negele’s flow meters:

  • Positive pressure operation
  • Full liquid fill at measuring point
  • No signal noise
  • Extremely robust flow meter
  • No electronics that could be damaged
  • Very compact flow meter
  • No conductivity needed (i.e. demineralized water)
  • Very fast response
  • Easy to inspect, maintain, and repair
  • 3A approval, and hygienic design
  • Low cost alternative to magnetic flowmeters

SENSOTECH – Green & Black Liquor Treatment in the Pulp & Paper Industry

In the pulp and paper industry, one process is the alkaline sulphate process, where lignin needs to be separated from the fibrous material.  The chemicals which are used in this process, need to be recycled.

To better monitor each step in this process, from black liquor to green liquor, and finally to white liquor, LiquiSonic® analyzers from Sensotech work perfectly.

With LiquiSonic®, one can follow a quality control plan that will increase productivity.


LiquiSonic® measuring technology allows the company real-time monitoring, green liquor generation, regulated and optimized, so that quality and precise results are born.

The base material in the liquor recycling process is black liquor. While burning an inorganic salt-rich smelt is formed, sediments form on the ground of the recovery boiler and have to be diluted by water or weak white liquor. The result of this process is green liquor, rich in Na2S and Na2CO3. The green liquor is often collec­ted in a separate stabilizing tank before it is clarified. While clarification of green liquor takes place, dregs have to be removed. The clarified green liquor is used for causticizing of regenerate NaOH.


The advantages of utilizing the LiquiSonic® technology are numerous:

  • Accurate inline concentration measurement of green, white and black liquor
  • Easy to clean
  • Operational safety is enhanced
  • Maintenance free
  • Ideal lime dosage
  • Reduced laboratory costs

LiquiSonic® sonic velocity measurement in green liquor


The LiquiSonic® flange sensor has an easy installation process for pipelines transporting green liquor.

With the LiquiSonic® controller 30, you can connect up to 30 sensors, so in this way multiple measuring points can be monitored:

  • after dilution tank
  • after stabilizing tank
  • after clarifier

UWT LEVEL CONTROL – The Industry Award “Industriepries 2017″

At Morton Controls, we are always very proud when one of our suppliers achieves a milestone.

Just recently, UWT Level Control was awarded the “Industriepreis”, which is given to the most innovative and advanced company, in the industries of medical technology, automotive and their suppliers.

Companies with high values in technology, economic, social, and environmental areas were awarded the Huber Verlag für Neue Medien GmbH”, a very prestigious acknowledgement.

A panel of 30 professors and trade journalists, decided that UWT deserved the award of BEST OF 2017 for their RFnivo® 3100 with anti-corrosive PFA coating level limit switch.

A little background on the solution, that UWT developed, came from the need for a more accurate measurement instrument, particularly where dust from aggressive media occurs. Mediums such as acids, heavy metals, and sulphur oxides, can cause inaccuracy, as well as time delays, and a drop in revenue down the line.

The RFnivo® 3100 capacitive level limit switch works in conjunction with the process to extract the dust of flue gases. The material used in this switch is corrosion-resistant, and coated with PFA Teflon®. Certain sections of the process connection thread are made of PTFE, meaning that all component parts are completely corrosion-protected.

You are looking at a longer-life product, which in time will save you money.

For more info on the RFnivo® 3100 with anti-corrosive PFA coating level limit switch, reach out to us at Morton Controls, and we will be happy to assist.
