Design and Development of a Sensor for Measuring Fat Content in Milk using Ultrasonic Technology

---

Abstract

This paper presents the design and development of a sensor which uses the Ultrasonic Technology to find out the important Parameters of Milk Sample which is directly comes from the Farmers in Raw form. The basic parameters include FAT, SNF, & CLR which is the tools for estimating the Real Value of Milk in terms of money to be paid and quality as well. The sensor is used the ultrasonic technology for detecting these parameters. A sample is withstand in the brass tube which is like as a solenoid to heat the sample up to 44 degree and then a beep of ultrasonic wave which is generated and transmitted from one end the tubes and go through the sample and received at the other end of the solenoid tube. This beep is going through the milk sample which directly energies the fat globules at the two temperatures. at44 and 60 degree. The acoustic impedance is taken from these two-temperature level and mean value is founded. Which corresponds to the fat contents. This is low cost and efficient tool to identify the basic parameters of milk sample.
