SmartMeasurement™’s products have been used successfully in a variety of flow measurement applications in the Pulp and Paper industries. The SmartMeasurement™ ALMAGWP magnetic flow meters with ceramic lining are used in highly abrasive slurries, while the standard ALMAGWP series meters are used for any conductive liquids including water and lime mud, liquid additives such as dyes, bleaches, water, and diluted powdered- in-water. The ATMF series thermal mass flow meters are used to measure flows of natural gas used for fuel in burners as well as air/fuel balancing applications. Any liquids with low conductivity which cannot be measured with magnetic flow meters as well as high viscosity fluids are an excellent candidate for the SmartMeasurement™ ALCM Coriolis mass flow meters. SmartMeasurement™ provides a one-stop shop for all flow metering requirements in the pulp and Paper industries.
Natural gas flow monitoring
The amount of chemical recovery that takes place in pulp and paper mills has a direct impact on its profitability. Lime is an important chemical used in the mill cooking process and the lime kiln consumes tremendous amounts of fuel that can be very costly to its recovery. Lime mud and water in the recovery process are an excellent application for the SmartMeasurement™. ALMAGWP series of Magnetic flowmeters with many choices of electrodes and liners.
Our ATMF series thermal mass flow meters with its exceptional accuracy enables proper natural gas/air ratio for maximum efficiency in the cooking process. The ATMF series thermal mass flow meters have no moving parts and all welded 316L stainless steel construction. The SmartMeasurement™ ATMF features mass measurement of very low flow rates with wide turndown capabilities and no pressure drop in the process media.
• The SmartMeasurement™ ATMF air mass flow meters, with its no moving parts and wide turn-downs are used for combustion air system as well as fuel gas to boilers.
• Lime mud and water in the recovery process are an excellent application for the SmartMeasurement™. ALMAGWP series of Magnetic flowmeters with many choices of electrodes and liners.
Ceramic Lining for use with Abrasive Fluids
Additives like Titanium dioxide or Calcium carbonate as well as pigment slurries, milk of lime or chalk suspension contain more and more solid material which requires a flow meter that can withstand abrasive liquids. Magnetic flowmeters, been used successfully for flow measurement in the pulp and paper industry for many years. Its main advantage is straight and free sensor tube which does not produce any unwanted pressure loss and is easy to clean. To ensure correct measurement, these flowmeters are provided with an insulating lining. However for highly abrasive applications, SmartMeasurement™ ALMAGWP series of Magnetic flowmeters with the ceramic liner option and electrodes considerably increase the operating life of highly abrasive applications. An example is the sand trap downstream of the fourth cleaner stage. A flowmeter with standard PTFE lining was able to resist to the demanding operating conditions for approximately two months, only. The device with special ceramic lining is still working perfectly after a operating life of already 1.5 years. The ALMAGWP series of Magnetic flowmeters with the ceramic liner option, come with either HART or MODBUS communication protocol and are available from 25-150mm (1-6”).
Mass flowmeter for measuring the concentration of additives
In paper production it is extremely important to measure out the various additives to ensure product quality. Liquid additives such: dyes, bleaches, powdered products diluted in water, and liquids with a low conductivity and/or high viscosity are used in various processes in a paper mill. Starch additives are used in recycled papers to increase strength of the cardboard. The starch arrives at the mill in powder form with various particle sizes and moisture content and is stored in silos. Using a variable speed auger the starch is then mixed with water in a small tank and then pumped into the piping system for transportation to the cooking system. Maintaining the correct water to starch balance is critical in this process. The SmartMeasurement™ ALMAGWP series of Magnetic flowmeters offers an economic choice in measuring starch water.
Starch must be cooked properly to ensure that the finished product has a consistent quality and thereby accurate mass balancing is needed between the cooking additives. The concentration of the starch in water and mass of the dry product must be as consistent as possible. Historically Magnetic flowmeters were used to obtain the measure of additives as well as water, however being a volumetric flowmeter; it cannot accurately determine the mass of each additive in the process. A more prices solution in this application has been the use of the SmartMeasurement™ ALCM Coriolis mass flow meters for direct mass measurement. The ALCM series replaces the existing volumetric flowmeters with the more precise mass flow measurement of the concentration of a solid diluted in water. The density measurement which was obtained experimentally can be directly measured with the SmartMeasurement™ ALCM Coriolis mass flow meters. Concentration values are sent to a control room via MODBUS and the concentration of the liquid will be controlled (in this case starch) at different temperature levels. The use of the mass flowmeter during the cooking phase allows consistency of the concentration values of starch to be achieved, which means that the quality of the final product is more consistent, and within the manufacturing tolerances required.
• The SmartMeasurement™ ALCM Coriolis mass flow meters have proven successful in measure both mass flow and density in starch additive applications.
• The SmartMeasurement™ ALMAGWP series of Magnetic flowmeters offers an economic choice in measuring starch water.
