EVM430-FR6047: EVM430-FR6047 clamp-on transducers without amplifiers

Part Number: EVM430-FR6047


I am using EVM430-FR6047 with 1MHz transducers and Clamp-on-V placement for 3/4 PVC pipe. Receive a signal, but it does not give the correct measurements.

Can the FW be adjusted to work with this signal without adding amplifiers?
What is the minimum signal amplitude and offset relative to zero involve for correct operation?
What types and diameters of pipes is it possible to work without amplifiers with Clamp-on-V or Clamp-on-Z?
