Systems, apparatuses, and methods for fluid flow detection

A method of manufacturing, the method comprising:

• providing a flow channel having an inlet port and an outlet port, wherein the flow channel is configured to receive a fluid via the inlet port and discharge the fluid via the outlet port;
• providing a pressure sensor having a first port and a second port;
• providing a first pressure sensor tube coupled to the first port;
• providing a second pressure sensor tube coupled to the second port;
• providing a first diaphragm disposed between the first port and the first pressure sensor tube and a second diaphragm disposed between the second port and the second pressure sensor tube, wherein the first diaphragm is in fluid communication with the inlet port and the second diaphragm is in fluid communication with the outlet port, wherein the pressure sensor comprises a pressure diaphragm and a frame, wherein the pressure diaphragm is configured to move along the frame to determine a pressure difference between the inlet port and the outlet port;
• and
• providing a computing device, the computing device configured to determine a flow rate of the fluid based at least on the pressure difference.
