Non-Contact Liquid Volume Gauge

Project Summary

Measuring the liquid volume in tanks with irregular shapes, containing non-homogenous liquids, or in dynamic conditions has been a challenge for years.

• We have developed an innovative non-contact acoustic method using a single and simple probe.
• Successful proof-of-concept tests have been conducted at the bench scale over a range of conditions.
• We are seeking commercialization partners

Test Results

• Resonant frequencies for determining volume are clearly defined.
• The volume for a spherically shaped tank is accurately measured.
• Volume measurements under transient conditions are within experimental error.

Benefits

• This non-contact gauge can accurately measure liquid volume in a tank.
• The tank can be irregularly-shaped.
• Dynamic conditions producing non-level liquid surfaces have no effect on gauge accuracy.
• This method is insensitive to solids, foams, or other liquid inhomogeneities.
• It offers cost advantages over exciting methods.
