Promoted products of the Ministry of Construction, calculate each drib and drab.
Usage: used for measuring total water volume of drinking cold water of flow running water pipeline.
Characteristic: the starting flow of the water meter increases five to eight times by comparing with common water meters, can avoid water using of drainers effectively, urge users to repair the phenomenon of emitting, dripping and leaking of pipelines and raise awareness of water saving, the inlet ends adopt single valve structure, which cant be used normally when upside-down charging, the water saving length and size are almost the same as common meters, and the installation is very convenient.
Range of application: water temperature≤*0℃, water pressure ≤1Mpa
The maximum permissible error:
1)   The maximum permissible error is ±5% in low pressure from including the minimum flow rate (Q1) to except transitional flow-rate (Q2)
2)   The maximum permissible error is ±2% in high pressure from including the transitional flow-rate(Q2) to including the overload flow-rate(Q4).
 
Economic benefits:
1)   Small caliber water-saving meter:
The starting flow rate of water-saving meters is very small and can calculate each drip. So water-saving meters can bring great economic benefits to water supply enterprises, and by comparing with common meters, water-saving meters improve more than *0.0L/h in sensitivity, the expense of taxation of each cubic meter is about RMB *7.6 Yuan, the cost is low.
2)   Big caliber water-saving meter:
Take DN*0 water meter as an example, the stone cavern flow rate improves about **0L/h by comparing with common water meters
Which can reduce water loss:
**0X*4X**5=******0L/year,for each year
