Volumetric Rotary Piston Water Meter

The volumetric water meter measures the volume of the actual fluid passing through the water meter. The most like the metaphor of large supermarkets or hotels in front of the kind of turn, only in a fixed direction of rotation, each turn a certain angle, the fluid on the water meter to the other side. So the volumetric water meter to measure the speed of the water meter to be more accurate. The velocity meter's measurement error is ± 2% error depending on the velocity of the fluid, and the volumetric water meter error can be controlled at ± 0.5% or less.
A water meter, or a quantitative discharge water meter, which is installed in a pipe consisting of a known volume of fluid and a fluid-driven mechanism.
Volumetric water meters generally use piston structure.
Unlike the speed meter, the volumetric water meter measures the volume of the actual fluid passing through the meter. The most like the metaphor of large supermarkets or hotels in front of the kind of turn, only in a fixed direction of rotation, each turn a certain angle, the fluid on the water meter to the other side. So the volumetric water meter to measure the speed of the water meter to be more accurate. The velocity meter's measurement error is ± 2% error depending on the velocity of the fluid, and the volumetric water meter error can be controlled at ± 0.5% or less.
From the use of said, volumetric water meter because of the effect of accurate measurement, are generally used for Seiko enterprises or test testing and other places; and speed water meter is generally used for normal life and other industrial water.
