We recommend reading this before using the Solids Flow Calculation Program to understand how this particular calculator it is applied. In factory the solids flow measurement normally takes place when solid objects are in the form of small particles. These might normally be crushed materials or powders

 

This is carried by a conveyor belt system or by some other host material. As an example -if solid materials are suspended in a liquid , the combined fluid is normally called a slurry e.g Limestone Slurry which can then be pumped through pipes similarly to a liquid.

For calculating the volume flow of a liquid with a known velocity through a particular pipe size, please use the Liquid Volume Meter Calculator instead

This Solids Flow calculator has been designed to help someone who is using some sort of conveyor system to move the solids.

is the equation being used.

How it is applied?

For solid objects, the flow usually is described by a specification of the mass or weight per unit time that is being transported by the conveyor system. The units will be in many forms, for example, kg/min or Ib/min. To make a measurement of flow, it is only necessary to weigh the quantity of material on some fixed length of the conveyor system. Knowing the speed of the conveyor allows calculation of the material flow rate.

In Figure Dwg 1.0 , a typical conveyor system is shown where material is drawn from a hopper and transported by the conveyor system. Assuming that the material can flow freely from the hopper, the faster the conveyor is moved, the faster material will flow from the hopper, and the greater the material flow rate on the conveyor. In this case, flow rate can be calculated in various units including Kilograms per minute kg/min or Pounds per minute lb/min and other useful units of Flow Measurement.

Thus The solids flow meter can calculate Flow or Q

As an example  (using Dwg 1.0)

W = weight of material on section of length L (in this example 100 lb)
R = conveyor velocity/speed in ft/min (in this example 2 ft/min)
L = length of weighing platform in ft (in this example 15 ft)
Q = Solids flow is calculated as 13.342144 lb/min

it is evident that the flow sensor is actually the assembly of a conveyor, hopper opening, and weighing platform. It is the actual weighing platform that performs the measurement from which flow rate is determined yet we  see that flow measurement is “weight measurement”
