The Laser Manhole Guard_LROB01-S is a battery powered smart sensordeveloped for continuously monitoring the gas valves andrelated connectors in the manholes of gas pipe lines. As the gasvalves aged in the harsh environment, a small leakage may occurThe leaked gas will accumulate in the closed space to anexplosive level, a potential public hazard. The laser manholeguard is based our proprietary highly-reliable laser methanesensing technologies. No maintenance or calibration is needed inthe life time of the device. In addition, specially designedultralow power laser chips make the battery to last 3-8 yearswithout recharge. The device is sensing the well for a settingtime interval and sending the results to the customer's datacenter, ensuring the health of the valves watched for 24-7dramatically reducing the human patrol cost.
