Teco Peoples Gas hits the road in one of their new methane detection vehicles. These vehicles are going to be game changers for Peoples Gas. The Ford Escapes are outfitted with MobileGuard, a cutting-edge, laser-based analyzer that uses special software and windspeed calculations to pinpoint natural gas leaks by locating methane emissions. The sensitive sensors can detect with ultra-high precision – parts per billion, as compared with our handheld leak detection equipment which detects parts per million. That means they will detect methane emissions that you can’t smell and would otherwise go unnoticed. And, the system is smart enough to know if the methane detected is from natural gas or other sources like biogas from sewers.
