ABSTRACT:
A device for measuring fluid density, the device comprising a silicon substrate having a micro-engineered cantilevered beam fabricated on it for use as a density sensor. The beam is at the end of a tube and has a contact manufactured on its end and a contact manufactured on the substrate below the contact. Means for causing said structure to vibrate and for detecting a characteristic of the vibration are provided, the characteristic being dependent on the density of the fluid to be measured.
