Hi Experts,

i have small confusions where can i connect the transducer the below document shows i need some correction(add resistor, capacitor) then the document does not show the transducer connection so kindly guide me to the correct path

HI Surya,

See the thread below regarding the connection.

To use the EVM430-FR6043 for water metering evaluation, you need to replace the R and C as described in the document. If you are using the board for gas metering, no change is needed and the transducers connect to X1 and X2. Gas metering requires an external amplifier and that is disconnected when evaluating for water metering.
