Is the water consumption the same for vertical installation and horizontal installation of water meters?

It's different. The water meter installed horizontally is generally installed on the water pipe, and the water flows along the direction of the water meter, so the water flow can be accurately measured. The vertically installed water meter is installed on the water pipe, and the direction of water flow is perpendicular to the direction of water meter, so there will be some errors in water flow. Water meter is an instrument for measuring water flow, mostly the cumulative flow of water, which is divided into two types: volumetric water meter and speed water meter.
