YUTECH FLUID-DENSITY-BRIX ANALYZER CUM CONTROL SYSTEM AND MOTORIZED FLUID-DENSITY SENSOR

BASIC SCIENCE BEHIND FLUID-DENSITY-BRIX:

Fluid-Density: the Density of a particular Fluid.
Density: is defined as" Mass per unit volume", which means it is the Mass contained in a fixed volume. It is denoted by "p" which is a Greek Letter called "Rho".
Density can be derived using the formula "p = m/v" where p is the Fuild-Density, m is the Mass and V is Volume. The unit to measure Fluid- Density is kg/m3 (Kilogram per cubic meter).
Brix: the measurement in percentage by weight of sucrose in pure water solution.
Online Direct measurement of Brix in a Process Fluid is difficult, so indirect methods are used.
The most popular ways of measuring Brix are:
- Hygrometric and Refractometric (Lab Methods).
- High-Frequency or Radio-Frequency Conductivity Type Brix Sensing.
- Microwave Type Brix Sensing.
- Fluid-Density Type Brix Sensing.
While Conductivity or Microwave methods are very successful in measuring Brix of "B and C" Massecuite in CVP, Brix of Sugar Melt, and Brix in a Molasses Conditioner unit, they cannot measure Brix of "A" Massecuite as we measure the Fluid's electrical quality which is variable.
Fluid-Density Measurement using a Motorized Stirring Sensor proves very successful as it directly measures the Fluid's mechanical quality of Fluid irrespective of its electrical characteristics. Thus measured Fluid-Density Value is further processed in the Fluid-Density- Brix Equation, to derive Fluid-Density-Brix.

APPLICATION IN SUGAR PROCESS OR SUGAR REFINERY:

SALIENT FEATURE:

Fluid-Density Type Brix Analyzer System targets sensing the Fluid-Density of Liquids, Slurries, or Syrups like Sugar Massecuite, Sugar Syrup, Sugar Melt, Liquors, and Molasses.
The Motorized Fluid-Density Sensor is specially designed to be inserted in a vessel to stir the Fluid Media and Measure its Fluid-Density, which can be expressed in simple terms as the Tightness or Thinness of a Fluid Media. It can also be informally referred to as the Consistency of the Fluid and is a Mechanical Property of a Fluid, which in Liquids is directly proportional to its Viscosity.
The Motorized Sensor's torque and power required to stir the Fluid varies with varying Fluid-Density.
Thus, the Motorized Fluid-Density Sensor's Power Consumption is directly proportional to the Fluid' s Density.
The Fluid-Density-Brix Analyzer's highly accurate Sensing Circuitry senses variation in the Motorized Fluid-Density Sensor's Power Consumption. This deviation is further processed to Derive the Raw Fluid-Density Value.
The Raw Fluid-Density Value is Linearized in the YUTECH Fluid-Density-Brix Equation.
The YUTECH Fluid-Density-Brix Equation is a complex Mathematical Algorithm with Built-in Fuzzy Logic that Accurately Analyzes, Calculates, and Derives the Fluid-Density-Brix Value from the Raw Fluid-Density Value.
This derived Fluid-Density-Brix Value is further analyzed and processed to compensate for Massecuite / Syrup Level variation within the Vessel.
Fully Compensated and Accurate Fluid-Density-Brix Value is Displayed and Transmitted for Controls.
