LXS-15E旋翼式水表机芯

详细介绍

 

1. Product Introduction

Use: Used to measure the total amount of cold water (or hot water) flowing through the tap water pipe.

 

2. Main features

The movement is a wet water meter movement of the rotor, with high measurement accuracy, the initial flow is small, to keep the counting mechanism of full irrigation (filled with water), anti-fouling performance, easy to read, beautiful appearance, safety and health, long life Features. 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. 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%
