we are using TDC 1000 in our work, and we saw a driver circuit used in sample schematic which was there in Ti website.. could you please explain whether its necessary to use this driver circuit for water flow metering
Hello Annie,
Thanks for posting to the sensing forum! TDC1000 is not our recommended device for flow metering due to its low accuracy, the recommended solution for high accuracy flow metering is the MSP430FR6043 which can be found here: https://www.ti.com/product/MSP430FR6043
In regards to TDC1000, there is a 200 ohm resistor on TX that is typically used for reducing amplitude and impedance matching to the transducer. RX includes a 300pF series cap as shown in the EVM schematic below.
