Title: Microfluidic aspirator and multi-purpose flow sensor and methods of making and using the same

Abstract

Devices that include a liquid chamber including at least two ports, wherein the opening of a first port is larger than the opening of a second port, an air chamber including at least one port, and a membrane located between the liquid chamber and the air chamber, and a pressure sensor coupled to the port in the air chamber are provided. Systems including the disclosed devices are also provided. The systems include liquid in the liquid chamber of the device. Methods of using the devices and systems include measuring one or more properties of a liquid by flowing the liquid through the liquid chamber of the system and measuring the pressure produced due to the difference in size of the ports in the liquid chamber.
