Product Description
- The water meter meets the requirements of GB/T 778-2007/ISO 4064:2005 standard.
- Wide range R=100/160.
- Meter reading data collection is accurate to 1 liter.
- Using copper ring cover, higher reliability (not the product of aluminum alloy cover on the market).
- Import-resistant nylon material is used instead of ordinary glass with a thickness of 11mm, and the maximum pressure resistance is 40kg, so it is not afraid of secondary water pressure.
- Freeze-proof, imported nylon material instead of glass will not freeze and crack within minus 30℃.

Note: The actual dial mark shall prevail. Maximum allowable error:
a) The maximum allowable error in the low zone including the minimum flow (Q1) to excluding the boundary flow (Q2) is ±5%
b) The maximum allowable error from the boundary flow (Q2) to the high zone including the overload flow (Q4) is ±2%
