Other Parts Discussed in Thread: MSP430FR6047
I am using TDC1000-TDC7200 ICs in a water flow measurement application, The Piezo used is of 1MHz frequency. I am able to sense the water flow and compared it with the standerd / caibrated flow meter. The problem is not getting consistency in the flow readings, sometimes getting below 1% error and sometimes it goes up to 9% error for the same flow rate. Also getting a lot of fluctuations in the delta TOF counts even at the zero flow rate.
Can anybody help me out to get improved accuracy/repeatability in flow measurement?/ I have used the reference schematic and routing pattern of TDC1000-7200EVM to design a flow meter.
