Eastern Instruments - Solids Mass Flow and Air Flow Measurement Equipment

There are many different ways to move solid materials through a process, ranging from belt conveyors, vibratory conveyors, and pneumatic systems, to bucket conveyors/elevators and screw conveyors.  Many of these devices are great for moving the product, but if you need to measure the mass flow rate or control the flow rate, pulsations created by some of these devices can cause major problems. Devices like bucket conveyors/elevators, rotary valves, and screw conveyors have pockets, flights, or buckets that help to collect the product and move it through the device.  These create pulses or slugs of flow, some of which can be very large and there can be seconds or even moments where there is no flow at all between slugs. Pulsating Flow through a CentriFlow Meter Most mass flow meters require that pulsations be mechanically smoothed if at all possible, because they cannot deal with the pulsations when measuring the flow and computing the totalization.  This is typ...

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...

Measuring the mass flow rate and totalization of a dry solid material can be difficult when that product is a hard to handle powder.  Product characteristics like particle size, cohesiveness, flowability, bulk density can all affect the accuracy of the mass flow measurement of a powder.  Below we will look at these characteristics in more detail and discuss how the CentriFlow Solid Mass Flow Meter is suited to deal with issues from these characteristics, making them non-issues or helping to eliminated/overcome them to get the best accuracy possible. CentriFlow Meter - Type II Configuration Particle Size: Particle size can become an issue when a material's particles get down to the powder regime, around 0.0394" or 1000 microns (18 mesh) and smaller.  The smaller the particle, usually the more trouble it can be to handle and therefore to measure.  However, there are definitely small particles that are not an issue, like sand, which can fall into the 0.0098" or ...
