LXSY-20F半液封水表机芯（摄像专用款）

1. Product Introduction

Use: record the total amount of cold water flowing through natural water pipes

2. Main features

The movement of the counting mechanism of the word wheel count part of the special liquid package, the whole surface of the long-term and antifreeze. The upper part of the wheel is equipped with a sealing ring to prevent the water inside the seal and the external counter to exchange water, to keep the character display part of the clear. The use of the movement of the general mechanical water meter can be upgraded to two kinds of remote function with a water meter. The first class is a mechanical water meter with additional intelligent camera recognition components, which can realize the function of reading the data of the meter. The picture can be displayed on the computer terminal, and it is easy to deal with the dispute. The second category is attached to the pulse sensor mechanical water meter, pulse signal can be processed to achieve the remote data reading table data, and easy to install. The above two types of mechanical water meters of the technical indicators are in line with national GB / T 778.1 ~ 3-2007 level measurement standards (equivalent to the international standard ISO 4064-1 ~ 3: 2005.IDT level) requirements.
