详细介绍

1. Product introduction

Usage: Measure the amount of cold water (hot water) flowing through the water pipe.

2. Main features

The distinguish characteristics of Multi-Jet Wet Type Vane Wheel Water Meter are high measuring accuracy, and small start-up flow rate. It can keep the counting mechanism full (filled with water). The model has a lot of advantages, including antifouling, easy reading, nice appearance, safety, sanitation, long service life, and etc. The technical indicators are in line with national GB/T 778.1~3-2007 level of measurement standards (equivalent to the international standard ISO 4064-1~3: 2005.IDT level) requirements.

3. Service conditions

a)Temperature rating:T30(The cold water)T90(The hot water)

b)Pressure rating:Map10

c)Pressure loss rating:△P63

d)Upstream flow field sensitivity rating:U10

e)Downstream flow field sensitivity rating:D5

f)Non-measurable negative test

4.The indication error

a)Low area(Q1≤Q≤Q2)The maximum allowable error is ±5%

b)High area(Q2≤Q≤Q4)The maximum allowable error is ±2%
