Rotar wing type water meter （Cast iron）

The movement is made of 100% raw material, without any waste, which enhances the wear resistance and ensures the stability of the counting part. The counter is vacuum sealed and the built-in desiccant is a long-drying dial that is not easy to fog. The metering accurately reaches the standard of iso4064, which is ±5% from the large allowable error in the low zone including the small flow rate to the low zone excluding the boundary flow; the large range from the boundary flow including the high flow including the overload flow Allowable error cold water meter is ±2%.

Advantage:

1. Accurate and reliable measurement, durable.

2. A small number of impurities in the water block the water filter network, and the impact on the measurement accuracy is small.

3. Parts are not easy to wear.

4. It has a check valve to prevent fluid backflow.
