Dear forum members,
Hope you guys are doing well.
I have a query. At our metering station, a 10" NG USM is installed for volume measurement. At the downstream of our metering station, approximately after 2 KM of 14" underground pipeline, another 8" NG USM is installed at receiving station. There are differences in the meter reading of both USM, in range of approximately 1% to 8%.
As per my limited knowledge, this difference is due to the fact that the meters are far apart, which introduce some lag. Please correct me if I am wrong. I am seeking the reason behind this difference, please respond if you know it.
Your responses shall be highly appreciated.
Regards,

So, how can you possibly expect the meters to read the same?

You'll need the P,T 20-30 pipe diameters upstream, adjacent to the meter location, and the fluid properties.
Check the meter calculation sheet used by the supplier, for a start.

Most ultrasonic meters used for precise measurements include the corrections you are seeking.
