US 2023/0400433 A1 · METHOD AND SYSTEM FOR REMOTELY MEASURING PROPERTIES OF A FLUID

Abstract

Disclosed herein is a method and a system for remotely measuring the properties of a fluid. The system comprises a waveguide, a transducer, and a processing unit. One end of the waveguide is coupled to the transducer and the second end is immersed in a fluid. The transducer is aligned at a certain angle of excitation ranging between 0°-90° with respect to the waveguide such that it can transmit ultrasonic waves comprising at least two wave modes. A part of the at least two wave modes transmitted through the wave guide leaks into the surrounding fluid and the remaining part is reflected. The attenuation of the at least two wave modes is studied in various attenuation regimes ranging between 0-1200 kHz. The reflected at least two wave modes are transmitted to the processing unit for extracting various parameters. Based on the extracted parameters, different properties of the fluid are measured.

Dependent claims

A system for remotely measuring properties of a fluid, the system comprising:

a waveguide and an ultrasonic transducer, wherein the waveguide is an elongated structure having a first end connected with the ultrasonic transducer and a second end immersed in the fluid;
wherein the ultrasonic transducer is placed at the first end of the waveguide at such an angle that the waveguide transmits waves from its first end towards the second end in at least two wave modes at an operating frequency;
and wherein the system further comprises a processing unit, operably coupled with the ultrasonic transducer, the processing unit is configured to:
determine a time of flight and amplitude ratio of reflected waves received by the ultrasonic transducer in response to the waves transmitted from the first end of the waveguide;
and
measure the properties of the fluid, at the same operating frequency at which the waves are transmitted and reflected between the first end and the second end of the waveguide, based on the time of flight and the amplitude ratio determined.
