What are the definition and technical requirements of the “starting flow rate” for mechanical water meters?
The “starting flow rate” (designated as Q₁ in metrological standards) is defined as the minimum water flow rate at which a mechanical water meter can initiate rotation of its internal measuring mechanism (e.g., impeller) and perform valid volume measurement. Key technical requirements...Read more -
How are the maximum permissible error standards for mechanical water meters classified?
The maximum permissible error (MPE) standards for mechanical water meters are classified based on international/regional technical specifications (e.g., ISO 4064, OIML R49) and meter accuracy classes, with divisions primarily depending on flow rate ranges and meter types (volumetric or turbine-ty...Read more -
What factors will affect mechanical water meter’s work ?
The main factors affecting the metering accuracy of mechanical water meters are as follows: 1. Water flow rate: Deviations from the rated flow range (especially ultra-low or ultra-high flow) will directly reduce measurement accuracy. 2. Water quality: Impurities, sediment, or scale in water can w...Read more -
The working principle of mechanical water meter
The working principle of a mechanical water meter is based on the hydrodynamic effect: when water flows through the meter’s movement, it drives the impeller to rotate. The rotational speed of the impeller is directly proportional to the water flow velocity (and thus the instantaneous flow r...Read more -
