The vertical helix type water meter

Model:LXRG-40～200

1、Applications

To record the total volume of water passing through the water pipelines.

2、The characteristics

Ø  High accurancy,wide flow range

Ø  High sensitivity due to the vertical helix turbine directly magnetic coupling with the register.

Ø  Special straight pipes are not needed for installation,as the internal measuring unit with stainless steel filter for easy fitting and maintenance;

Ø  Removable measuring unit

Ø  Temper-proof internal adjusting device

Ø  High wear-resisting bearing for its stable operation and long life of measurement.

Ø  Hermetic sealed register

Note: 1 The water mwter complies with the standard of <<GB/T778.1~3-2007>>（ISO4064-1~3:2005,IDT）

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

3.Two types of the registers for option, the plastic cover register,type:P and glass cover register,type :M

3、Metrological requirements
