The volumetric water meter is also a type of water meter divided according to the measurement principle, which is different from the velocity water meter. What are the structural characteristics of the volumetric water meter? What are the practical applications?
Volumetric water meter: A water meter installed in a pipeline, consisting of a number of known volume chambers and a fluid driven mechanism that are filled and discharged by successive flows, or referred to as a quantitative discharge water meter.
A water meter, or quantitative discharge meter, installed in a pipe, consisting of a number of known volume chambers and a mechanism driven by a fluid that is continuously filled and discharged with fluid.
Positive displacement water meter generally adopts piston type structure.
Unlike velocity meters, volumetric meters measure the volume of the actual fluid that passes through the meter. The most vivid analogy is like the turnstile in front of a large supermarket or a hotel, which can only be turned in a fixed direction, and every time a certain Angle is turned, the fluid is turned to the other side through the water meter. Therefore, the measurement of the displacement water meter is more accurate than that of the velocity water meter. The measurement error of the velocity type water meter will have a ±2% error according to the different speed of the fluid, and the displacement type water meter error can be controlled at a level of ±0.5% or even lower.
In terms of use, the positive displacement water meter is generally used in seiko enterprises or test and other places because of its accurate measurement effect. The speed type water meter is generally used for normal domestic and industrial water.
In terms of price, displacement meters are generally much more expensive than velocity meters.
The structural characteristics and application of the displacement water meter are simply introduced to you, and you can deepen your understanding by combining the actual use.
