Part Number: TDC1000-GASEVM

can some detail how the receive signal is conditioned. is the ma 6 volt and min 1 volt?

30 volt pulse = 6 v recieve signal -1 to 0 and volt and 0 to 6v.

Any Feedback. Currently have a system using two sensor and need to understand how to make it work with one.

Fernando,

The receive signal path from the Transducer is through the Cap C7 & R13 back to the Rx1 pin of the TDC1000 on channel 1 & C10 R18 at channel 1.

Also this EVM was originally designed for gas flow metering and for flow metering we do typically use 2 transducer setup.

We recommend our customers use MSP430 based MSP430FR604X for accurate flow metering solution as in the link below:
