Maximum Permissible Error

a) In the lower zone (Q1≤Q﹤Q2)±5%

b) In the upper zone (Q2≤Q≤Q4); for water temperature up to 30°C±2% from 30°C up to 90°C ±3%

Applications: to record the total volume of water passed through the pipelines.

Characteristics: compact design, light weight, magnet transmission register which could be rotation in 360 for convenient reading.

Note:

1. The water meter complies with the standard of<<GB/T 778.1-3-2007>> (ISO 4064-1-3:2005, IDT）.

2.For hot water up to 90°C is available on request.

3.The water meter has two types of register:8 digital reading with 1 pointer(M) and 5 digital reading with 4 pionters(N)
