Vertical water meter

1. Purpose: To record the total amount of potable cold water flowing through the water pipe. 2. Features: The vertical water meter can be installed vertically on the pipe. Other features are similar to E-type meters and semi-liquid sealed meters. 3. Main parameters: a. Water meter: Water temperature ≤30℃, Water pressure ≤1Mpa b. Indicated error: Between the overload flow Q4 and the dividing flow Q2, the maximum error of the cold water meter is ±2%; between the dividing flow Q2 and the minimum flow Q1 (excluding the dividing flow Q2), the maximum error is ±5%. Note: The performance indicators of the water meter meet the ISO4064 international standard and GB standard.
