Adopting advanced technology, micro processor, technology of micro power consumption, Turbine Flowmeter Type QSY8504 is a intelligent flowmeter of great functions, high measuring precision, pretty pressing damage, anti-vibration, large measuring range, repeatability. It is used to measure industrial fuel gas, civilian fuel gas and natural gas. Function
1、intelligent integration, high precision and repeatability
2、Three power supplies of micro power consumption are adopted to insure safety and stability.
3、Reluctance sensor is adopted to realize low starting flow, pretty pressing damage and great anti-vibration.
4、Zero position is regulated automatically and zero drift is avoided.
5、E2PROM insures saving intrinsic parameters permanently.
6、It will alarm if voltage of battery is low (≤2.7V).
7、Coded lock against change of intrinsic parameters
8、Easy manipulation and multi interfaces of output
9、Imported sealed self-lubricated micro-moment bearing improves its service life.
10、Simple structure and easy installation and maintenance
11、Blasting resistance structure is acceptable for measuring explosive gases.
