LIQUID FEEDER
Principle and Operation
Whether liquids or powders the general principle of Rospen Industries Loss in Weight feed system is to accurately weigh and control the output of variable products either,
continuously or as a batch. As the name suggests, the Loss in Weight concept is primarily based around the application of a weigh system allied to PLC control, the specification for a liquid feeder system is shown below.
Liquid Feeder
Using exactly the same principle as described for powders, liquids can also be weighed to an accuracy + or – 0.5% where a loss in weight liquids vessel is mounted on a Rospen low profile loss in weight platform. By means of flexible pipes the vessel is connected to a header tank, comprising dump valve and variable speed discharge pump. The loss in liquid weight per unit of time is measured by the microprocessor and the pump speed modulated to hold the liquid loss- in-weight and thus output constant.
The system eradicates the need for flowmeters and also compensates for:
Varying densities
Temperature change
Viscosity variations
Pressure change
Rospen Standard Weigh Platform
The standard Rospen weigh unit, manufactured at the Stonehouse factory is of a robust design and provides for a maintenance free operation.
