Continuous measure,memory and show the volume of cold water of passing sealed full pipes under measurement condition.

This is Positive Displacement water meter which record the drinking water volume of passing pipe by piston driving that make use of actual measurement theory..It adopt magnet driver structure and possess better function of anti-inference.

Register and water was divided to make meter dial clearly.All material of used is suited for drinking water meter sanitary standard.

Its characters are low initial flow,more precise measurement,sanitation ,convenient reading.Especially it used for drinkable water quality and expensive water charge place.

Low area（Q1≤Q<Q2）max allowed error ±5％

T≤30℃,High area（Q2≤Q≤Q4）max allowed error ±2％
