Does the new water meter go slower than the old one?
First look at the table is what style, with some sideways, some never mind; as for the old water meter fast or slow, it is more complex, we still want to see what type of watch, you know, there are dozens of meter subdivision series, each series characteristics are not the same, and the influence of the length of time the different tables are not the same.
Because of the current domestic water environment problems, China is basically using speed water meter, both at the speed of water flow to measure. Because the old water gauge will have sediment (scale), so the caliber will gradually become smaller, pressure will change in the same case faster!
The water meter is not slow, the old water meter has been used for a long time, because of the mechanical friction between the gear and gear, the resistance increases. The new water meter because the indicators and mechanical gears are very good, so the measurement is more accurateAccording to what you say, if the slope is not very large, there is little effect on the speed of the water meter, but the horizontal water meter does not meet the specifications of the water meter installation if it is inclined to mount
