Скачать или смотреть DN15 Light blue volumetric water meter，

Light blue volume water meter is a kind of water meter based on the principle of volume measurement, its shell is usually light blue, both beautiful and a certain degree of corrosion resistance.

Working principle: the volume type water meter generally adopts the piston type structure, and has one or more known volume compartments inside. When the water flow is out of date, the water flow drives the piston and other rotating elements to rotate or move regularly. Every time the filling and discharging is completed, it is equivalent to a certain volume of water flow through the water meter. The counting mechanism records the rotation times, so as to calculate the total water flow.

Performance Characteristics
High measurement accuracy: through fixed volume measurement, the error can be controlled at ±0.5% or even lower, especially for small flow and low flow rate.
Good stability: it is not sensitive to flow fluctuations and can maintain high measurement accuracy under unstable flow conditions.
Easy maintenance: the structure is relatively simple, there is no complex electronic components inside, the maintenance cost is low, and it is easy to repair or replace parts.

Wide range of application: not only can be used for clean water measurement, but also for liquid containing a small amount of impurities, and even some viscous liquid flow measurement.

Application scenarios: Due to accurate measurement, it is often used in places with high measurement accuracy requirements such as seite enterprises and experimental tests, and can also be used in some civil buildings with high accuracy requirements for water metering.
Installation and maintenance: installation shall be carried out in strict accordance with the instructions, usually requiring to reserve enough straight pipe sections. In daily maintenance, attention should be paid to the water quality, to avoid excessive impurities in the water leading to wear or blockage of internal moving parts, affecting the measurement accuracy and service life.
