Technically @kezo is right about measuring temperature drop for balancing but it assumes a well designed system and flowrates within design limits. Our house is anything but and when we moved in the heating was all over the place. I resorted to opening all the lockshields and going round feeling by hand for the same temperature in each radiator as the system warmed up, progressively turning lockshields down starting nearest the boiler. Took about 5 mornings to get it right. I know if I measured flow and return ttemperature on each radiator they would be very wrong, but what I achieved works.
