Due to test system limitations, the maximum controlled flow rate generated in testing was 11.2 liters per minute. The meter under test uses a DRV5013 Hall sensor with four disc magnets, and a horizontally configured flow meter (see Figure 4-1). Reference flow rate was measured using an industrial-grade magnetometer flow meter in series with the mechanical flow meter. Flow rate simulations estimate the 3D-printed flow meter to be capable of accurately sensing in excess of 30 L/min before concerns of non-linearity. Linearity is expected to decrease with flow rates less than 2 L/min. If the desired flow rate exceeds the suggested limits of the 3D-printed design, it may be necessary to re-size the flow meter for more accurate results.
