Industrial use gas meter
STRUCTURE
LMN series gas meter is an assembled type gas meter developed by combin-ing Chinese national conditions. It consists of outer casing, measuring unit and index. The outer casing is drew by high quality cold-rolled steel plate and this guarantees the reliable sealing for gas meter. The connection between the upper casing and the lower casing adopts bolting joints and this not only ensures the reliable sealing, but also is convenient for future maintenance for the meter
PRODUCT FEATURES
High-quality cold-rolled steel plate is adopted to make the outer casing, electrophoretic coating, the diaphragm adopts special rubber, the value and value seat adopts specialized thermosetting phenolic plastics and it has good stability and good corrosion resistance and long service life; computer automatic controlled testing, small error and high accuracy testing result. The complete meter has good sealing and pressure tight performance, stable performance, accurate measurement, safety reliability, long service life and beauty appearance. It is widely used for measuring flowrate of town gas, natural gas and L.P.G. etc.
EXECUTING STANDARD
The products execute GB/T 6968-1997 diaphragm gas meter Grade B standard and JJG 577-2005 diaphragm gas meter standard and OIML R31-1995 diaphragm gas meter international ttandard, products’ durability executes Europe standard EN1359:1998, main technical index listed below is the actual inspection standard for meters to leave the factory.
