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. To form a movement in the form of table-based form of a relatively improved, can be improved for the magnetic sensor with a table, no magnetic sensor with a form of smart IC card form, wired remote form of the table, wireless Remote form of the table and so on, and the application of a wide range of reliability. The technical indicators of its base table are in line with national GB / T 778.1 ~ 3-2007 level measurement standards (equivalent to the international standard ISO 4064-1 ~ 3: .IDT level) requirements.
