Tendo is a technology company that provides innovative, economical solutions to accurate flow rate and pressure measurements that are extremely challenging to obtain. We seek to leverage the advancement and expertise in high fidelity flow measurements developed in Princeton’s Mechanical and Aerospace Engineering Department to drastically improve the fidelity of flow sensing at a significantly reduced cost. We are commercializing a new invention developed at Princeton called the Elastic Filament Velocimetry (EFV, patent pending), based on a novel yet simple microribbon structure, which resulted in a highly sensitive sensor that can detect flow rates as low as 0.5mL/hour – smaller than any technology available.
