Wireless remote transmission meters made by ZHEJIANG SAPPHIRE METER is a new high-tech measuring meter which accords with standards of GB/T6968-1997<Diaphragm Gas Meter>, CJ/T112-2008<IC Card Diaphragm Meter>and JG/T162-2009<Remote Transmission Meter Reading System for Residence>. This kind of meter has the functions of wireless automatic data reading, automatic counting, anti-theft, status monitoring, and valve control etc. Through low-energy consuming wireless communication technology wireless remote transmission meters can automatically read and monitor gas data. It solves the difficulties of indoor reading, delayed data transmission and inconvenient management. This makes gas consumption more humanistic for users to use gas before they actually pay for it. This kind of meter has good cost performance and especially suitable for household gas measurement. It is one of the best gas measuring instruments for modernized gas management.
