Hello,
I'm trying to make a water flow meter using TDC1000 and TDC7200 and I'm using audiowell 1Mhz tranducer with plastic tubing (part number is HS0014-000 model number is RC15/HS-US0004-000-01)
I successfully get data from ultrasonic transducers but my problem is automatic channel swapping is not working so I'm only be able to get data upstream or downstream what can I do to make the channel swapping work? Thank you.
My TDC1000 register settings as follows;
CONFIG_0 - 0x4A
CONFIG_1 - 0x41
CONFIG_2 - 0x12
CONFIG_3 - 0x08
CONFIG_4 - 0x1F
TOF_1 - 0xE4
TOF_0 - 0x32
TIMEOUT - 0x03
CLOCK_RATE - 0x01
My zero flow and downstream graphis as follows;
my zero flow and upstream graphic as follows;
My attempt to make automatic channel swapping and result graphis as follows;
