Eastern Instruments - Solids Mass Flow and Air Flow Measurement Equipment

Not all Solids Mass Flow Meters are created equally, so how do you know which meter is best suited to measure your product??? When asking this question, the best answer is, when in doubt, test some product!  Most manufacturers of mass flow meters should have a test lab and a list of products that they have tested with their devices, building a database of what works and what does not work. WHAT TO LOOK FOR WHEN EXPLORING THE TESTING OPTION? REPLICATE THE INSTALLATION - Testing a product sample should also be done in a way that replicates the application or installation location.  This means that the equipment being used for testing should be similar to that of what will be used in the field.  For example, if the application calls for a flow meter (flowmeter) to be installed under the discharge of a screw conveyor, then the testing lab should have a screw conveyor.

When measuring the flow rate and totalization of a bulk solid materials with a flow meter, there are a lot of options.  However, when the particles of the bulk solid are large, irregular shaped, and vary greatly in bulk density, the options quickly dwindle down to a few. Large Bulk Materials like tobacco, recycled plastic bottles, recycled carpet pieces, trash, construction debris, biomass feed stocks (like wood products, hay, straw, and leaves) and the like are not only difficult to move through a process, but their product characteristics make it almost impossible to accurately measure the flow. Biomass Materials - Hay/Straw Biomass Materials - Wood Chunks/Chips Recycled Plastic Bottles Construction Debris To get an accurate mass flow measurement of bulk solids with large particles and irregular product characteristics the mass flow meter that is used must be able to measure the flow and have no dependence on these varying product characteristics like bulk de...

Weigh Belt Feeders have been widely used for many years to measure the flow rate and totalization of solid materials in a process while providing a feed device to move materials through that process.  For some products they can be accurate enough to keep in your process and deal with their calibration issues, but for some products, they can be a maintenance nightmare and something that needs to be replaced.  However, with their large footprint and complex installation, finding a replacement feeder that fits can be a real issue. One way to deal with this maintenance issue but to still have that vital process measurement is to install a flow meter that can be installed at the end of a belt conveyor.  Since the Weigh Belt is in essence a belt conveyor, it would be used as just a material handling device and not a flow meter.  Once such a device that can fit in such a tight space is the CentriFlow Type I meter from Eastern Instruments.

A question that we get asked a lot is "why do I need a Solids Flow Meter?" or "how can a Solids Flow Meter help my plant or process?"  To answer these questions, we first will look at what a Solids Flow Meter is and then where/how it can be implemented. CentriFlow Solids Mass Flow Meter from Eastern Instruments DEFINITION OF SOLIDS FLOW METER: Solids Flow Meters can be called many things from Flow Meters, Flow Instrumentation, Process Measurement Devices, or even just Process Meters.  A Solids Flow Meter can be considered an device or point measurement, that when placed in a process, provides a window into what is going on in the process.  It is an instrument that provides vital process flow data like Flow Rate and Totalization/Totalized Weight.  This can be on a continuous process or on a batch process.  The Flow Rate would be in mass units like lb/hr, kg/hr, Ton/hr, MTon/hr, etc, and the Totalization/Totalized Weight would be in mass units like lb, kg...
