Title: | Improved Variable Frequency Ultrasonic Interferometer for Velocity and Attenuation Measurement in liquids |
Area: | Physical Sciences |
Focus Area: | Purity & Uniformity Detection |
Patent: | IN201Technology Demonstration11036499 |
Social Benefits: | Attenuation measurement facility added which is not present in the commercially available instrument, Generation of RF signal based on Direct Digital Synthesis (DDS) technology, Compatible with existing commercial liquid cells, Measurement of parameters at harmonic frequencies, Low cost solid-state electronic circuit design for the excitation and detection of ultrasound, Provision to count number of maxima and minima, Low excitation voltage produces negligible heat in the liquid sample. |
