Volumetric water meters measure the volume of actual fluid passing through the water meter. The most vivid metaphor is like the kind of revolving door in front of a large supermarket or hotel, which can only be rotated in a fixed direction. Every time it turns a certain angle, the fluid will turn to the other side through the water meter. Therefore, the measurement of
volumetric water meters is more accurate than that of speed water meters. The measurement error of the speed type water meter will have an error of ±2% according to the speed of the passing fluid, while the error of the volumetric water meter can be controlled at a level of ±0.5% or even lower.
Installed in a pipeline, a water meter consisting of a number of chambers of known volume that are successively filled and discharged with fluid and a mechanism driven by fluid, or a quantitative discharge water meter for short.
Volumetric water meters generally use a piston-type structure.
Unlike velocity water meters,
volumetric water meters measure the volume of actual fluid passing through the water meter. The most vivid metaphor is like the kind of revolving door in front of a large supermarket or hotel, which can only be rotated in a fixed direction. Every time it turns a certain angle, the fluid will turn to the other side through the water meter. Therefore, the measurement of

In terms of use,
volumetric water meters are generally used in seiko enterprises or test and testing places due to their accurate measurement effect; while speed water meters are generally used for normal domestic industrial water.
In terms of price, volumetric water meters are generally much more expensive than speed water meters.
