ora wireless remote gas meter with steel case is a new high-tech measuring meter which accords with standards of GB/T6968-1997
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.
