Lora wireless remote gas meter with aluminum case IWG1.6B～IWG6B
Product introduction
Lora wireless remote gas meter with aluminum case 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>. 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. It 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.
Basic functions
-Automatic valve shut down function: If there is power outage, the low battery voltage or the function failure will turn off the valve automatically
-Alarm function: alarm triggered when power supply under low voltage or there is interferences with meter faults
-Display function: LCD screen can display the cumulative use of gas, valve status and other information
-Two-way data transmission function: through hand-held device and meter management systems to achieve two-way data, Keep running information of the meter updated
-Keep gas consumption data records
-Against gas theft and against magnetic interference function
-Remote meter reading functions: data collection for single-users or communities
-Wireless data collection and control functions: real-time monitoring the operational status of gas meter to check whether the user's gas equipment is running correctly. Meters can be connected to collection and hand-written devices. Through controlling device the valves can be turned on and off. Parameters can be retrieved and modified.
-Protections: turn off valves when encountered magnetic interference, the battery running out or sensors abnormal.
