Products Description
Due to its high accuracy and low starting flow rate (sensitivity to minute water flows), volumetric water meters are primarily used in the following scenarios where high measurement precision is required or flow rates are relatively low.
Product features
Higher Measurement Accuracy: Especially Solving the Problem of "Low-Flow Under-Registration"
This is the core advantage of volumetric water meters.
Principal Difference:
Volumetric water meters (such as the commonly used single-jet or multi-jet meters in households) rely on water flow velocity to drive the impeller. When the flow rate falls below the minimum starting flow (Q1)-for example, in cases of faucet drips, slow drainage from water purifiers, or hot water tank refills-the impeller may fail to rotate, leading to "measurement failure." In contrast, volumetric water meters can precisely record consumption even at extremely low flow rates (below 0.5 L/h) through the reciprocating motion of internal components.
For Users: Prevents "hidden water charges" caused by unmeasured drips (e.g., with pipeline micro-leaks, volumetric meters may not register usage for months, but once the leak is fixed, normal metering resumes and the bill appears to increase).
For Water Utilities: Reduces "non-revenue water (NRW)" from metering under-registration. For example, in Malta, volumetric water meters reduced low-flow under-registration by 40%, directly cutting NRW by 4%.
Wider Measuring Range: Adaptable to "Variable Flow Conditions"
Volumetric water meters can cover the full spectrum of applications-from microflows (such as drips), to low and medium flows (such as typical household usage), up to relatively high flows-without the need to change meters according to different flow conditions.
Old Network Renovation: Suitable for Complex Flow Conditions
In aging urban water supply networks, issues such as pipe degradation and uneven pipe diameters often lead to turbulent flow and irregular velocity distribution. Under such conditions, Volumetric meters tend to show increased measurement errors (over ±5%). Volumetric water meters, however, are insensitive to flow profiles. Even in turbulent environments, their "fixed-chamber measurement" ensures accuracy. This makes them the preferred choice for meter replacement in old residential areas, helping utilities more accurately determine actual water supply volumes and better assess network leakage.
