This paper reviews our recent work on vibrating sensors for the physical properties of fluids,
particularly viscosity and density. Several device designs and the associated properties …

An apparatus and method is described for measuring non-invasively level of contents inside
an array of containers without setting up any electrodes or attaching sensors around the …

A low cost, fast yet highly accurate method for determining liquid level inside small
containers is described. The non-invasive technique can easily resolve sub-1% levels in …

Measurement of the small filling levels in closed steel container systems is still a challenge.
Ultrasound, however, is a sensitive and non-invasive technique and is suitable for online …

A non-invasive liquid level sensing system for monitoring the amount of liquid in at least one
container includes a platform for supporting the at least one container, at least one holder …

By simulating the sound field of a round piston transducer with the Kirchhoff integral theorem
and analyzing the shape of ultrasound beams and propagation characteristics in a metal …

(57) ABSTRACT A non-invasive level sensing system for monitoring the amount of
contentinat least one container includes a platform for Supporting the at least one container …

In recent days, measuring a liquid level of molten metal is difficult in furnace. At the same,
excess quantity of molten metal leads to increase the cost. The sufficient molten metal is …

Free vibration occurs when a mechanical system is disturbed from equilibrium by an
external force and then it is allowed to vibrate freely. In free vibrations, the system oscillates …
