Pneumatic Flow Meter



As part of the project related to soft robotics, it is required to measure the flow rate and therefore allows for the total amount of energy to measured. The Flowmeter is constructed with a nylon CNC machines impeller with a segmented disc printed on top with an IR detector mounted on top to measure the rate at which the disc rotates at. Currently, the specification of this module is a psi rating of 5-80 and an lpm of 10-40.

The impeller housing was machined from a solid block of aluminium and CNC on my custom CNC machine.


The CAM was processed on Fusion 360 and the CNC was controlled with Mach3…

The next stage is to make the impeller, this was done with an adaptive tool path along with a tragic 2D contour, which resulted in lifting the part out of the work holding.
