Water meter readings 22mm vs 15mm?

[Pieter]

Good day

My question is concenrning a system where the main water meter is on a 22mm water line, this line is then split to 15mm lines.
Will the 22mm line water meter have a larger reading over the 15mm line water meter?

All water meters are calibrated to read the volume of water that flow through them, it doesn't make any difference what the pipe / meter size is.
A larger / smaller meter or a larger / smaller pipe connected to the meter won't affect the reading.
